Official Raspberry Pi OS Is Now Based on Debian GNU/Linux 11 “Bullseye”

Filed under

The latest Raspberry Pi OS release, dated October 30th, 2021, is the first to switch bases from the old-stable Debian GNU/Linux 10 “Buster” to the Debian GNU/Linux 11 “Bullseye” operating system series, and it uses the Linux 5.10.63 LTS kernel by default.

But the Debian Bullseye rebase is just the cherry on top, as the newest Raspberry Pi OS release features all of its desktop components and applications build against the GTK+ 3 open-source application framework for the in-house built PIXEL desktop environment based on LXDE.

Raspberry Pi OS Updated For Debian 11 Bullseye

  • Raspberry Pi OS Updated For Debian 11 Bullseye, Desktop Transitions To GTK3+Mutter

    Raspberry Pi OS as the official operating system for the Raspberry Pi single board computers has been updated against Debian 11 "Bullseye".

    Raspberry Pi OS has shifted its package base from Debian 10 to Debian 11 now that Bullseye is out as stable and in good shape the past few months. Besides upgrading the underlying packages against the new Debian release, Raspberry Pi OS has finished migrating its own desktop components from GTK2 to GTK3. The Raspberry Pi desktop should now be in good shape and happily running on GTK3. GNOME's Mutter has also replaced Openbox as the window manager used on Raspberry Pi OS.

Raspberry Pi OS upgraded to Debian 11

  • Raspberry Pi OS upgraded to Debian 11 "Bullseye" - CNX Software

    Debian 11 “Bullseye” was released in August 2021, and I was expecting Raspberry Pi OS to soon get upgraded to the latest version, especially the last time around, in 2019, Raspian Buster was released even before the official Debian 10 “Buster” release, although the reason was Raspberry Pi 4 launch.

    This time around it took longer, but the good news is that Raspberry Pi OS has just been upgraded to Debian 11, meaning it benefits from the new features such as driverless printing, in-kernel exFAT module, “yescrypt” password hashing, and packages upgraded to more recent versions.

  • Bullseye! Debian-based Raspberry Pi OS scores an update with 'less closed-source proprietary code'

    It's been a while, but the Raspberry Pi OS has had a major version bump, taking this flavour of Linux for the diminutive computer to Debian Bullseye.

    Debian Bullseye debuted in August, and the Raspberry Pi team admitted that getting its eponymous operating system updated had "taken a bit longer than we'd hoped".

    Bullseye will be supported for five years, and makes use of version 5.10 of the Linux kernel. It came just over two years since the last major Debian release, Buster. As well as the changes under the hood, the Raspberry Pi OS incarnation has a number of tweaks in support of the computer's hardware and the OS's desktop environment.

Time to update your Raspberry Pi with the new OS...

  • Time to update your Raspberry Pi with the new OS based on Debian 'bullseye'

    It's that time! The Raspberry Pi OS (formerly known as Raspbian) has done a major upgrade moving the package base from Debian buster to Debian bullseye.

    A long time coming, since bullseye was released back in August. Supported for at least five years, this brings with it tons of major upgrades to all the internals. Not only that though, the RPi team also updated their desktop (based on LXDE) with a number of extra tweaks to make it look and feel better.

    While it's been around for years now, this release has only just done the jump from GKT+2 to GTK+3. This is the toolkit used for actually drawing the interface giving you buttons, menus and everything else in the form of widgets. In the announcement post the team grumbled a bit that GTK+3 took a while to move to, as it's more difficult to use and it "removed several useful features which we relied upon" but they've found workarounds for a few bits they wanted.

    This release also moved their window manager from Openbox to Mutter which comes with visual effects, rounded corners, shaded borders, window animations and more. In other words, it's all a bit more modern looking and feeling. On top of that it also makes it easier for them to support Wayland in future too although they're still "quite a long way" from switching to Wayland. A drawback though, is that the OS now needs at least 2GB RAM.

"Now running on Debian 'bullseye' Linux"

  • Raspberry Pi OS: Now running on Debian 'bullseye' Linux

    Debian 11, dubbed 'bullseye' and the successor to 'buster', arrived in August and now the makers of the Raspberry Pi have finally updated Raspberry Pi (RPi) OS to this version.

    The move to Debian 11 for Raspberry Pi OS took a little longer than expected and doesn't bring a huge amount of changes from the Debian side. However, there are several changes that come from the RPi side.

  • Debian 11 Based Raspberry Pi OS 2021-10-30 Update Available to Download -

    Debian 11 Based Raspberry Pi OS 2021-10-30 Update Available to Download, Raspberry Pi OS is a Debian-based distribution custom-built for Raspberry Pi computers. The development team have published a new version of Raspberry Pi OS which carries the code name “Bullseye”.

    The new version is based on Debian 11 and upgrades a number of desktop components. “All of the desktop components and applications are now using version 3 of the GTK+ user interface toolkit. GTK+ is a layer of software that applications can use to draw standard user interface components (known as ‘widgets’) such as buttons, menus and the like, so that all applications have a consistent look and feel. Up until now, most of the desktop has used version 2 of the GTK+ toolkit, but increasing numbers of Debian applications are using GTK+3, so to try and keep things consistent, we’ve upgraded all our software and the desktop itself to the newer version. GTK+3 has been around for several years now, and people have occasionally asked why we didn’t move to it before now. The simple answer is that many things are much easier to do with GTK+2 than with GTK+3, particularly when it comes to customising the appearance of widgets – GTK+3 has removed several useful features which we relied upon. It has ended up being necessary to find work-arounds to a lot of these – hopefully no one will notice them and everything will still work as before!” Additional details can be found in the project’s release announcement.

  • Bullseye – the new version of Raspberry Pi OS

    Every two years, Debian Linux, on which Raspberry Pi OS is based, gets a major version upgrade. Debian ‘buster’ has been the basis of Raspberry Pi OS since its release in 2019, and Debian ‘bullseye’ was released in August. (As some of you may know, Debian name their versions after characters in Disney/Pixar’s Toy Story films – Bullseye was Woody’s horse in Toy Story 2.)

    The latest Raspberry Pi OS release switches to Debian 11 “bullseye” and offers the GTK+3 UI toolkit and the “mutter” window manager, which requires 2GB RAM. Meanwhile, the upcoming Linux 5.16 will include mainline support for the RPi CM4.

    Raspberry Pi announced the release of a new version of Raspberry Pi OS (formerly Raspbian), which advances to the Debian 11 “bullseye” release. Debian 11.0 was released in August as a major upgrade from the two-year old Debian buster.

  • New Raspberry Pi OS Includes Hidden Speed Boost and 64-Bit Option

    The latest Raspberry Pi OS has today been announced, and it sees a number of changes under-the-hood, and a few that will be noticeable by end users. Chiefly, a new window manager, "mutter" which requires Raspberry Pi models with 2GB of RAM of greater. In a hidden bonus, YouTuber Jeff Geerling has confirmed that some Raspberry Pi 4 owners may see a speed boost built-in to the latest release and a possible new 64-bit release.

    For its "Bullseye" release we mainly get a number of behind the scenes updates, including a speed boost for those of us lucky to have new BCM2711 SoC with a C0T model number. these chips appear on newer Raspberry Pi 4, Compute Module 4 and Pi 400 boards and it appears that for the Pi 4 and CM4 you get an extra 300 MHz performance boost, 1.8 GHz, vs the stock 1.5 GHz. Owners of older Raspberry Pi 4 with B0T model numbers can still manually overclock their Pi.

    The new Raspberry Pi OS is still based upon a 32-bit release, but it appears that there is also a 64-bit release, lurking in the shadows and spotted by Geerling. Whether this is still a beta or ready for release remains uncertain.

Raspberry Pi OS Finally Hits Bullseye With Debian 11 Update

  • Raspberry Pi OS Finally Hits Bullseye With Debian 11 Update Bringing Several Upgrades | HotHardware

    The biggest change is support for version 3 of the GTK+ user interface toolkit. This is a software layer that provides a graphical user interface (GUI) for widgets like buttons, menus, and so forth. Most desktop apps have, up to this point, used version 2 but as an increasing number have begun leveraging version 3, the Raspberry Pi Foundation felt it was time to make the switch.

    It sounds like this wasn't necessarily an easy decision. In a blog post, Raspberry Pi Foundation's Simon Long explains that many thing are simply easier to do with version 2, especially as it pertains to customizing the look of widgets. He also notes that version 3 removed several user features, necessitating certain tweaks, like the new appearance of tabbed interfaces for widgets.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.
