System76 Meerkat Mini-Linux PC - Now with Up to Intel Core i7-1260P (liliputing.com) 26

Liliputing.com has an update about the System76 Meerkat, which they describe as "a compact desktop computer with support for up to 64GB of RAM, up to two storage devices (for as much as 16TB of total storage), and up to an Intel Core i7 mobile processor. It's basically a rebranded Intel NUC." (Escept that System76 offers a choice of Pop!_OS or Ubuntu Linux pre-installed.)

"Previously available with a choice of 10th or 11th-gen Intel Core processor options, the Meerkat now also supports 12th-gen Intel chips." That means there are a total of 9 different processor options available. Prices start at $499 for an entry-level model with a Core i3-10110U processor, 8GB of RAM and a 128GB SSD. The prices rises by $50 if you want to go with a Core i3-1135G4 model, while prices start at $599 for a Meerkat mini PC with a 12th-gen Intel Core processor....

But the biggest difference is that Intel's 12th-gen processors introduce a hybrid architecture that pairs Performance and Efficiency cores, leading to much higher core counts for better multi-core performance.

New 'Ubuntu Flatpak Remix' Has (Unofficial) Flatpak Support Preinstalled (9to5linux.com) 37

An anonymous reader shares this report from 9to5Linux: After Canonical's announcement that future Ubuntu releases won't include Flatpak support by default, someone already made an unofficial Ubuntu flavor that ships with support for Flatpak apps preinstalled and working out of the box, called Ubuntu Flatpak Remix.

Meet Ubuntu Flatpak Remix, an unofficial Ubuntu derivative that doesn't feature support for Snap apps and comes with support for Flatpak apps working out of the box. Several key apps are preinstalled in the Flatpak format rather than as a Snap app, including the Mozilla Firefox web browser, Mozilla Thunderbird email client, and LibreOffice office suite.... Support for the Flathub portal is installed as well, so you'll be able to install more apps with just a few clicks.

Asahi Linux Disputes Report That Linux 6.2 Will Run on Apple M1 Chips (twitter.com) 40

Last week ZDNet reported Linux had added upstream support for the Apple M1 Pro, M1 Max, and M1 Ultra chips and then concluded that "newer Mac owners can look forward to running Linux on their M1-powered machines."

Saturday Asahi Linux called ZDNet's story "misleading and borderline false," posting on Twitter that "You will not be able to run Ubuntu nor any other standard distro with 6.2 on any M1 Mac. Please don't get your hopes up." We are continuously upstreaming kernel features, and 6.2 notably adds device trees and basic boot support for M1 Pro/Max/Ultra machines. However, there is still a long road before upstream kernels are usable on laptops. There is no trackpad/keyboard support upstream yet.

While you can boot an upstream 6.2 kernel on desktops (M1 Mac Mini, M1 Max/Ultra Mac Studio) and do useful things with it, that is only the case for 16K page size kernel builds. No generic ARM64 distro ships 16K kernels today, to our knowledge.

Our goal is to upstream everything, but that doesn't mean distros instantly get Apple Silicon support. As with many other platforms, there is some integration work required. Distros need to package our userspace tooling and, at this time, offer 16K kernels. In the future, once 4K kernel builds are somewhat usable, you can expect zero-integration distros to somewhat work on these machines (i.e. some hardware will work, but not all, or only partially). This should be sufficient to add a third-party repo with the integration packages.

But for out-of-the-box hardware support, distros will need to work with us to get everything right. We are already working with some, and we expect to announce official Apple Silicon support for a mainstream distro in the near future. Just not quite yet!

Microsoft .NET 8 Will Bolster Linux Support (infoworld.com) 51

An anonymous reader shared this report from InfoWorld: .NET 8, the next planned version of the Microsoft's open source software development platform, is set to emphasize Linux accommodations as well as cloud development and containers.

A first preview of .NET 8 is available for download at dot.microsoft.com for Windows, Linux, and macOS, Microsoft said on February 21. A long-term support (LTS) release that will be supported for three years, .NET 8 is due for production availability in November, a year after the release of predecessor .NET 7.

The new .NET release will be buildable on Linux directly from the dotnet/dotnet repository, using dotnet/source-build to build .NET runtimes, tools, and SDKs. This is the same build used by Red Hat and Canonical to build .NET. Over time, this capability will be extended to support Windows and macOS. Previously, .NET could be built from the source, but a "source tarball" was required from the dotnet/installer.

"We are publishing Ubuntu Chiseled images with .NET 8," adds Microsoft's announcement.

And when it comes to the .NET Monitor tool, "We plan to ship to dotnet/monitor images exclusively as Ubuntu Chiseled, starting with .NET 8. That's notable because the monitor images are the one production app image we publish."

Ubuntu Flavors Agree to Stop Using Flatpak (phoronix.com) 117

Phoronix reports: While Ubuntu Linux hasn't provided Flatpak support out-of-the-box due to their preference of using their own Snap app packaging/distribution format, Ubuntu flavors/spins have to this point been able to pre-install Flatpak support if they desired. However, for the 23.04 "Lunar Lobster" cycle and moving forward, Ubuntu flavors will no longer be permitted to install Flatpak packages by default.

Flatpak support for Ubuntu and its flavors will remain available in the Ubuntu archive so those wanting to install Flatpak support can easily do so post-install.

This change going into effect with the 23.04 cycle is making it so no Ubuntu flavors will have Flatpak support installed by default / out-of-the-box: they are supposed to center around Debian packages and Snaps for their out-of-the-box packaging support to align with Ubuntu.

From the blog OMG Ubuntu: Ubuntu developers have agreed to stop shipping Flatpak, preinstalled Flatpak apps, and any plugins needed to install Flatpak apps through a GUI software tool in the default package set across all eight of Ubuntu's official flavors, as of the upcoming Ubuntu 23.04 release.

Ubuntu says the decision will 'improve the out-of-the-box Ubuntu experience' for new users by making it clearer about what an "Ubuntu experience" is....

As far as Ubuntu is concerned, only deb and snap software is intrinsic to the 'Ubuntu experience', and that experience now needs to be offered everywhere. Flavor leads (apparently) agree, and have all agreed to mirror regular Ubuntu by not offering Flatpak features in their default install for future releases....

Flatpak will not be uninstalled or removed when user makes the upgrade to Ubuntu 23.04 from a version where Flatpak is already present.

Linux 6.2: The First Mainstream Linux Kernel with Upstream Support for Apple M1 Chips Arrives (twitter.com) 65

Steven Vaughan-Nichols, writing for ZDNet: Linux 6.2 was released yesterday, and Linus Torvalds described the latest Linux kernel release as, "Maybe it's not a sexy LTS release like 6.1 ended up being, but all those regular pedestrian kernels want some test love too." For once, I disagree with Torvalds. By adding upstream support for the Apple M1 Pro, M1 Max, and M1 Ultra chips, newer Mac owners can look forward to running Linux on their M1-powered machines. And, for techies, that's sexy. Getting Linux to run on the M1 family wasn't easy.

When these high-powered ARM chips first arrived, Torvalds told me in an exclusive interview that he'd like to run Linux on these next-generation Macs. But, while he'd been "waiting for an ARM laptop that can run Linux for a long time," he worried, saying, "The main problem with the M1 for me is the GPU and other devices around it because that's likely what would hold me off using it because it wouldn't have any Linux support unless Apple opens up."

UPDATE (2/26/2023): Asahi Linux called ZDNet's report "misleading and borderline false," posting on Twitter that "You will not be able to run Ubuntu nor any other standard distro with 6.2 on any M1 Mac. Please don't get your hopes up." We are continuously upstreaming kernel features, and 6.2 notably adds device trees and basic boot support for M1 Pro/Max/Ultra machines.

Firefox

What's New in Firefox Version 110.0? (omgubuntu.co.uk) 63

Valentine's Day saw Mozilla releasing version 110.0 of its Firefox browser. OMG Ubuntu highlights some of its new features: Firefox already supports importing bookmarks, history, and passwords from Microsoft Edge, Google Chrome, Chromium, and Safari but once you have the Firefox 110 update you can also import data from Opera, Opera GX, and Vivaldi too — which is handy.

Other changes in Firefox 110 include the ability to clear date, time, and datetime-local input fields using using ctrl + backspace and ctrl + delete on Linux (and Windows) — no, can't say I ever noticed I couldn't do that, either.

Additionally, Mozilla say GPU-accelerated Canvas2D is now enabled by default on Linux, and we can all expect to benefit from a miscellaneous clutch of WebGL performance improvements.

PikaOS Is a Next-Gen Linux Distribution Aimed Specifically Towards Gamers (zdnet.com) 48

An anonymous reader quotes a report from ZDNet, written by Jack Wallen: PikaOS is very similar to that of Nobara Linux, which opts for a Fedora base. But what are these two Linux distributions? Simply put, they are Linux for gamers. [...] So, what does PikaOS do that so many other distributions do not? The most obvious thing is that it makes it considerably easier to install the tools needed to play games. Upon first logging in, you're greeted with a Welcome app. In the First Steps tab, you have quick access to tools for updating the system, installing patented codecs and libraries, installing propriety Nvidia drivers, installing apps from the Software Manager, and installing WebApps.

Next comes the Recommended Additions, where you can install the likes of: PikaOS Game Utilities is a meta package that installs Steam, Lutris, GOverlay, MangoHud, Wine, Winetricks, vkBasalt, and other gaming-centric tools; Microsoft TrueType fonts for better Windows font emulation; Blender for creating 3D images; OBS Studio for streaming; Kdenlive for non-linear video editing; Krita for painting; and LibreOffice for productivity. In the Optional Steps tab, you can add AMD proprietary drivers, ROCm drivers, Xone drivers, and Proton GE (for Steam and Wine compatibility). Finally, the Look And Feel tab allows you to customize themes, layouts, and extensions. The layouts section is pretty nifty, as it allows you to configure the GNOME desktop to look and feel like a more traditional desktop, a MacOS-like desktop, a Windows 11 layout, a throwback GNOME 2 desktop, and even a Ubuntu Unity-like desktop.

As far as pre-installed software goes, it's pretty bare bones (until you start adding titles from the Recommended Additions tab in the Welcome App). You'll find Firefox (web browser), Geary (email), Pidgin (messaging), Weather, Calculator, Cheese (web camera software), Rhythmbox, Contacts, a few utilities, and basic games. However, installing new apps is quite simple via the Software Manager app. Of course, the focus of PikaOS is games. When you install the PikaOS Game Utilities, you'll get Steam installed, which makes it easy to play an endless array of games on the Linux desktop. One thing to keep in mind, however, is that when you launch the PikaOS Game Utilities installation, it opens a terminal window to run the installation. Give this plenty of time to complete and, in the end, you can launch Steam, log in to your Steam account, and start playing. Just remember, the first time you launch the Steam app, it will take a moment to update and configure. But once it's up and running... let the games begin.

New Distro 'blendOS' Combines Arch Linux, Fedora Linux and Ubuntu (9to5linux.com) 73

"From the maintainer of Ubuntu Unity and the Unity desktop environment, here comes blendOS," writes 9to5Linux, "a GNU/Linux distribution that aims to be the last distribution you'll ever use, especially if you distro hop." blendOS is here to offer you "a seamless blend of all Linux distributions," as its creator wants to call it. blendOS is based on Arch Linux and GNOME on Wayland, but it lets you use apps from other popular distributions, such as Fedora Linux or Ubuntu.

This is possible because you can use the native package managers from Arch Linux (pacman — included by default), Fedora Linux (dnf), and Ubuntu (apt), which are included as containers using Distrobox/Podman. However, the DNF and APT package managers aren't included in the live ISO image, nor blendOS's own blend package manager.... It also follows a rolling release model, since it's derived from Arch Linux.

Even if it comes with the GNOME desktop by default on the live ISO image, blendOS will let you deploy a new installation with another popular desktop environment, such as KDE Plasma, MATE, or Xfce, or even window managers like Sway or i3. Apart from the fact that you can install any app from any of the supported Linux distributions, blendOS also comes with out-of-the-box support for sandboxed Flatpak apps, which you can easily install directly from the Flathub Store app, which is a Web App that puts the Flathub website on your desktop.

Wine 8.0 Released — and Plenty of Improvements are Included (omgubuntu.co.uk) 59

An anonymous reader shares this report from OMG! Ubuntu: Developers have just uncorked a brand new release of Wine, the open source compatibility layer that allows Windows apps to run on Linux.

A substantial update, Wine 8.0 is fermented from a year's worth of active development (roughly 8,600 changes in total). From that, a wealth of improvements are provided across every part of the Wine experience, from app compatibility, through to performance, and a nicer looking UI....

Notable highlights in Wine 8.0 include the completion of PE conversion, meaning all modules can be built in PE format. Wine devs say this work is an important milestone towards supporting "copy protection, 32-bit applications on 64-bit hosts, Windows debuggers, x86 applications on ARM", and more.

Canonical Announces General Availability of Ubuntu Pro, Free for Up to 5 PCs (9to5linux.com) 52

An anonymous reader quotes a report from 9to5Linux: Ubuntu maker Canonical announced Thursday the general availability of its Ubuntu Pro comprehensive subscription for Ubuntu users who want to expand the security updates and compliance of their systems.

First released in a beta version in October 2022 with free subscriptions for personal and small-scale commercial use on up to 5 machines, Ubuntu Pro is only available for Ubuntu LTS (Long-Term Support) releases, starting with Ubuntu 16.04, and promises up to 10 years of security updates, as well as access to exclusive tools. These include Ansible, Apache Tomcat, Apache Zookeeper, Docker, Drupal, Nagios, Node.js, phpMyAdmin, Puppet, PowerDNS, Python 2, Redis, Rust, WordPress, ROS, and many others.

The Ubuntu Pro subscription promises patches for critical CVEs in less than 24 hours and expands the optional technical support to an additional 23,000 open-source packages and toolchains beyond the main operating system, not just for Ubuntu's main software repository....

Canonical says that if you need Ubuntu Pro for more than five PCs, you will have to purchase a paid plan, which is currently priced at $25 USD per year for workstations or $500 USD per year for servers with a 30-day free trial. Official Ubuntu Community members get free support for up to 50 machines.

GNOME

83% of GNOME Users Installed Extensions, Survey Shows (omglinux.com) 86

Last summer GNOME invited people to voluntarily run the tool gnome-info-collect on their systems to send back (non-sensitive/non-identifiable) data about their system configurations. 2,560 people ran the tool, and they're now releasing the data.

Here's the distribution of distros for all 2,560 respondents:

Fedora: 1,376 (54.69%)
Arch: 469 (18.64%)
Ubuntu: 267 (10.61%)
Manjaro: 140 (5.56%)
EndeavourOS: 66 (2.62%)
Debian: 44 (1.75%)
openSUSE: 38 (1.51%)
Pop! 38 (1.51%)
Other: 78 (3.10%)


And the breakdown of hardware manufacturers (top four):

Lenovo: 516 (23.54%)
Dell: 329 (15.01%)
ASUS: 261 (11.91%)
HP: 223 (10.17%)


The site OMG! Linux pointed out that 90% of systems had Flatpak installed — (though it's enabled by default on Fedora, which was 54.69% of all the respondents). Some other interesting stats they noticed: - Most common default browser: Firefox (73.14%), Chrome (11.64%), Brave (4.76%). [Microsoft Edge was the default browser on 37 systems (1.51%) ]

- 83% of users have at least one (non-default) GNOME extension installed
- 'App Indicator' is the most popular extension (by 43% of those using extensions)

- GSConnect, User Themes, and Dash to Panel/Dock also widely used

- Most popular desktop apps: GIMP (58.48%), VLC (53.71%), Steam (53.40%)


[...] The popularity of GNOME extensions will surprise no-one. It is a solid indicator that the existing GNOME extension system is good at doing what it's there to: let users augment and extend their system in the ways they want.

GNOME's report adds that "it's exciting to see the popularity of new GNOME apps like Flatseal, To Do, Bottles, and Fragments."

One other interesting stat from their report: 55% of the participants were using Online Accounts, with Google the most common one added, followed by Nextcloud and Microsoft. But "Some of the account types had very little usage at all, with Foursquare, Facebook, Media Server, Flickr and Last.fm all being active on less than 1% of systems."

Vanilla OS Offers a New Take on Security for the Linux Desktop (vanillaos.org) 31

OS News cheers the first official release of Vanilla OS, calling it "an immutable desktop Linux distribution that brings some interesting new technologies to the table, such as the Apx package manager."

From the official release announcement: "By default, Apx provides a container based on your Linux distribution (Ubuntu 22.10 for Vanilla OS 22.10) and wraps all commands from the distribution's package manager (apt for Ubuntu). Nevertheless, you can install packages from other package distributions.... Using the --dnf flag with apx will create a new container based on Fedora Linux. Here, apx will manage packages from Fedora's DNF repository, tightly integrating them with the host system.
ZDNet calls Vanilla OS "a new take on Linux that is equal parts heightened security and user-friendly." Among other things, "the developers opted to switch to ABRoot, which allows for fully atomic transactions between 2 root partitions." The official release announcement explains: ABRoot will check which partition is the present root partition (i.e A), then it will mount an overlay on top of it and perform the transaction. If the transaction succeeds, the overlay will be merged with the future root partition (i.e B). On your next boot, the system will automatically switch to the new root partition (B). In case of failure, the overlay will be discarded and the system will boot normally, without any changes to either partition.
But ZDNet explains why this comes in handy: Another really fascinating feature is called Smart Updates, which is enabled in the Vanilla OS Control Center, and ensures the system will not update if it's either under a heavy load or the battery is low. To enable this, open the Vanilla OS Control Center, click on the Updates tab, and then click the ON/OFF slider for SmartUpdate. Once enabled, updates will go through ABRoot transitions and aren't applied until the next reboot. Not only does this allow the updates to happen fully in the background, but it also makes them atomic, so they only proceed when it's guaranteed they will succeed.

The only caveat to this system is that you are limited to either weekly or monthly updates, as there is no daily option for scheduling. However, if you're doing weekly updates, you should be good to go.... Setting aside that which makes Vanilla OS special, the distribution is as stock a GNOME experience as you'll find and does a great job serving as your desktop operating system. It's easy to use, reliable, and performs really well...especially considering this is the first official release.

"Every wallpaper has a light and a dark version," adds the release announcement, "so you can choose the one that best suits your needs."

Ubuntu Blogger Chooses the 5 Best Linux Distros of 2022 (omgubuntu.co.uk) 74

Long-time Slashdot reader destinyland shares an article listing "the five best Linux distros of 2022" — as chosen by the editor of the blog omg! ubuntu!

"Spoiler: they're not all Ubuntu-based!" the article begins, also noting that it's not a ranking of superiority of importance, but rather "giving a shoutout to some of the year's best Linux releases."

Its top-listed non-Ubuntu distro? Fedora Workstation 37
Fedora Workstation is a flagship desktop Linux distro for good reason: it's robust, it's reliable, it's impeccably produced — it distills what a lot of folks seek most: a "pure" GNOME experience, delivered as devs intend, atop a strong and stable base.

Autumn's offer of Fedora 37 Workstation features GNOME 43 — an update that majorly improves the GNOME Shell user experience with Quick Settings. There's also a more-featured Files rebuilt in GTK4/libadwaita; a revamped Calendar app; a Device Security panel; Raspberry Pi 4 support; GRUB instead of syslinux on BIOS; and more.

Folk often overlook Fedora Workstation because, as Linux distros go, it's rather understated, unassuming, and drama-free. Yet, it is a finessed and functional distro that forgoes fancy flourishes to focus entirely on its performance, its integration, and its cohesion.

If you've never tried Fedora you're missing out, so sort it!

There were two other non-Ubuntu distros on the list:
  • Manjaro 22.0 'Sikaris'. "As Arch-based Linux distros go Manjaro is one of the best.... Everything from the shell to the package manager to bespoke touches and apps are cohesive, considered, and choreographed. Manjaro 22.0 isn't just a distro, it's an experience."
  • Linux Mint 21. "As well as being easy to use, Linux Mint ships with an interesting selection of pre-installed software that aims to cover most users' needs, including some homegrown apps that are rather special."

Bug

Linux Kernel Security Bug Allows Remote Code Execution for Authenticated Remote Users (zdnet.com) 51

The Zero Day Initiative, a zero-day security research firm, announced a new Linux kernel security bug that allows authenticated remote users to disclose sensitive information and run code on vulnerable Linux kernel versions. ZDNet reports: Originally, the Zero Day Initiative ZDI rated it a perfect 10 on the 0 to 10 common Vulnerability Scoring System scale. Now, the hole's "only" a 9.6....

The problem lies in the Linux 5.15 in-kernel Server Message Block (SMB) server, ksmbd. The specific flaw exists within the processing of SMB2_TREE_DISCONNECT commands. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the kernel context. This new program, which was introduced to the kernel in 2021, was developed by Samsung. Its point was to deliver speedy SMB3 file-serving performance....

Any distro using the Linux kernel 5.15 or above is potentially vulnerable. This includes Ubuntu 22.04, and its descendants; Deepin Linux 20.3; and Slackware 15.

Data Storage

Linux Kernel Fixes Longstanding Bug in Its Handling of Floppy Disks (theregister.com) 57

"Linux kernel 6.2 should contain fixes for some problems handling floppy disks," reports the Register, "a move which shows that someone somewhere is still using them." This isn't the only such fix in recent years. As a series of articles on Phoronix details, there has been a slow but steady flow of fixes for the kernel's handling of floppy drives since at least kernel 5.17, as The Register mentioned when it came out....

Back in July 2016, SUSE kernel developer Jiri Kosina submitted a patch. The problem arose because this change broke something else and later got reverted, and so the problem hung around. In July last year, he sent in a new patch that fixed it again for the 5.12 kernel, and was later back-ported to 5.10, an LTS version, and again into kernel 5.15 — another an LTS version, and the one you're running today if you're on the current Ubuntu LTS release, or something built from it such as Linux Mint 21....

Now, in December 2022, a new patch for the forthcoming kernel 6.2 fixes a memory leak that dates back to 5.11 or before.

GUI

Windows 10 Users With Windows Subsystem For Linux Can Now Use GUI Apps (zdnet.com) 101

An anonymous reader quotes a report from ZDNet: Microsoft's Windows Subsystem for Linux (WSL) for running GNU/Linux environments on Windows 10 and Windows 11 has reached version 1.0.0 and is now generally available. Microsoft has been building WSL, including its own custom Linux kernel, for several years now. At first, WSL and WSL2 were an optional component within Windows, but last October Microsoft made the preview WSL available in the Microsoft Store as a separate app. The Store version could deliver users -- mostly developers and IT pros -- faster updates and features independently of updates to Windows.

As well as WSL shedding the "preview" label, Microsoft is making the WSL app from the Store the default for new users. As Microsoft noted last October at the release of Windows 11, the long term plan was to move WSL users to the Store version. However, Windows 11 still supported the "inbox version" of WSL while it continued developing the Store version. With this release, Microsoft is backporting WSL functionality to Windows 10 and 11 to make the Store version of WSL the default experience. The latest backport is available to "seekers" who click "Check for Updates" in Windows Settings, but in mid-December it will be pushed automatically to devices. The updates are available for Windows 10 version 21H1, 21H2, or 22H2, or on Windows 11 21H2 with all of the November updates applied.

Microsoft detailed a number of changes to commands now that the Store version of WSL is the default version, noting "wsl.exe --install will now automatically install the Store version of WSL, and will no longer enable the "Windows Subsystem for Linux" optional component, or install the WSL kernel or WSLg MSI packages as they are no longer needed." The virtual machine platform optional component will still be enabled, and by default Ubuntu will still be installed. One of the main new additions to WSL 1.0 is that users can opt in to support for systemd, the at-one-point maligned Linux system and service manager, which runs by default in several Linux distros, including Ubuntu and Debian. Also, Windows 10 users can use Linux GUI apps, a capability that was previously exclusive to Windows 11 users.

AMD

AMD Finally Opens Up Its Radeon Raytracing Analyzer 'RRA' Source Code (phoronix.com) 4

Michael Larabel, reporting for Phoronix: This summer AMD announced the Radeon Raytracing Analyzer "RRA" as part of their developer software suite for helping to profile ray-tracing performance/issues on Windows and Linux with both Direct3D 12 and the Vulkan API. Initially the RRA 1.0 release was binary-only but now AMD has made good on their "GPUOpen" approach and made it open-source.

As noted back in my original article from July on the Radeon Raytracing Analyzer release: "Radeon Raytracing Analyzer is hosted on GitHub but the only content in the actual Git repository right now is documentation, so it would appear that at least initially this is a closed-source package though some documentation also says it's MIT licensed."

Last week that was cleared up with the Radeon Raytracing Analyzer source code going public. There are build instructions for compiling the RRA 1.0 sources on both Microsoft Windows and Linux while the Linux instructions are tailoring to Ubuntu use. Building the Radeon Raytracing Analyzer depends upon the Qt 5.15 toolkit.

Vanilla OS: More Than Just Vanilla GNOME With Ubuntu (itsfoss.com) 39

Slashdot reader Soul_Predator writes: Vanilla OS is Ubuntu on stock GNOME, with on-demand immutability and package selection freedom. It is currently a beta project, with a stable release planned for the next month.
"The first-time setup process is a breeze to experience," writes It's FOSS News, applauding how it lets uses choose and enable Flatpak/Snap/AppImage.

Overall, a package manager that installs applications utilizing a container, getting the ability to choose your package managers, on-demand immutability, and vanilla GNOME make it seem like a good deal to keep an eye on... I'd say it is a project that I believe a lot of users will appreciate.

You can download the ISO by joining its Discord channel for now. The ISO is not yet publicly available to all. Take a look at its documentation if you are curious. However, as per the roadmap, they plan to have a release candidate soon enough.
