KaOS 2021.04

8 Giugno 2021



KaOS è una distribuzione Linux per desktop che utilizza l’ultima versione del desktop enviroment KDE, la suite office Calligra e altre applicazioni basate su Qt toolkit. E’ stata ispirata da Arch Linux, ma usa i propri repositori. KaOS è una rolling-release ed è compilata solo per i 64 bit.

Versione 2021.04

Questa versione contiene (in Inglese):

Time goes fast, it is eight years ago this week that KaOS started, so this is kind of an April anniversary release.

It has also been eight years that the same initramfs creation tool has been used (Mkinitcpio), but with Dracut being the more widely used and constantly maintained, it is time to move to this new tool for KaOS. For almost two years Mkinitcpio did not have a maintainer and upstream had talks about abandoning this tool. This will be a major change and will require lots of work for the ISO creation, but a start has been made, the linux-next kernel already defaults to Dracut for initramfs creation.

The tool to manage, search, and install KaOS Community Packages, kcp has been completely rewritten (still in Go) in order to support the main new feature: the configuration. Now, you can adapt kcp/pckcp to your needs in editing the configuration files (located in $HOME/.config/kcp/ directory). Notable options :

  • You can use another temporary directory (for installations through kcp) than /tmp
  • kcp can use a third organization for package management. The only constraint is the organization should be on Github
  • For install or download operations, the clone method can use either ssh or https
  • You can define a locale different from the system
  • You can use a custom PKGBUILD prototype to use for PKGBUILD generation through pcpkcp
  • You can add packages to ignore for depends when you check a PKGBUILD with pckcp

Other notable changes:

  • Improved performances on updating the database (which needed to completely refactor the database). The operation should be significantly faster.
  • Improved performances for the PKGBUILD parser. The scanner is more accurate and faster. Plus it is designed as an API in order to be usable for a third party app.
  • Some PKGBUILD checkers were added/modified/merged.
  • Added is a man page for pckcp. The man page for kcp was updated

The installer Calamares has picked up the transition to QML again. All navigation is now done in QML for KaOS. The Finished module was also ported to QML, this gives a simpler end page, with clear buttons showing two options. It also opened the way to give users a clear message regarding installation logs once the install is completed. Usersq is another module being ported to QML, a preview is included in this release, but is not the default users module yet.

The default mirror used for all KaOS installs is provided by Fosshost. Big change with Fosshost is that with just one mirror users will have access to a worldwide network of mirrors through Fastly CDN. No longer is there a need to adjust a mirrorlist, you will always be connected to the fastest mirror in your area.

As always with this rolling distribution, you will find the very latest packages for the Plasma Desktop, this includes Frameworks 5.81.0, Plasma 5.21.3, and KDE Applications 21.04.0. All built on Qt 5.15.2+.

This ISO means the end of the non-free Nvidia 340xx support in KaOS. This driver needed to be heavily patched since Linux 5.6, but now with Linux 5.11, loading the module completely fails SDDM. Since upstream pretty much abandoned this driver, it is time to remove from KaOS. Users with Nvidia cards prior to 2014 will need to switch over to the in-kernel modesetting driver or install nouveau.

New applications added include VSCodium. Also new is support for JPEG XL, a modern option (and probable future replacement) for JPEG. Integration in the system is provided by qt-jpegxl-image-plugin, this allows you to open & view .jxl files seamlessly in Gwenview.

Updates to the base of this distribution were numerous and include a new GCC 10.3.0, Glibc 2.33 & Binutils 2.36.1 based Toolchain, with most of the core being rebuild on this new Toolchain, Systemd 247.6, Proj 8.0.0, Git 2.30.1, LLVM/Clang 11.1.0, Protobuf 3.15, Krb5 1.19.1, Poppler 21.04.0, Mesa 21.0.3, NetworkManager 1.30.4, ZSTD 1.4.9, Samba 4.14.3.
Qt 5.15 does not receive updates or maintenance from the Qt company (only closed source, paid support is available). KDE has stepped up though and published a maintained 5.15 fork. KaOS now regularly does a patch update from this fork for all of Qt 5.15, so it basically is now at 5.15.3.
