Qt 6.5.1 was released today, and all of the kf6/plasma 6 stack will be updated/rebuild on that new Qt.
After that is done, it most probably is quite doable to use Plasma 6 as your daily driver for light work, so it is time to post some instructions.
The first step is the simplest one, and will not be explained here, since adjusting pacman.conf is by far the easiest part of any testing and if you do not know how to do that yet, moving to Plasma 6 is too soon for you.
- Edit pacman.conf and add the build repo above core, then add kde-next above build
- Make sure you have the needed applications already opened, if you plan to do this with a GUI
- Update the system after adding the new repos,
sudo pacman -Syu
- Remove the kf5 group
sudo pacman -Rncs kf5, this will remove all of plasma, all Qt 5 based apps, etc
- Plasma will close after this step, so no more panel and so on
- Install plasma 6,
sudo pacman -S kf6 kdeplasma6, after this step, panel will re-appear again
- Install commonly used KDE applications in their kf6 version, all named with
6 at the end, like dolphin6, kate6, konsole6, midna-themes6, octopi6
- Check the online package viewer, kde-next repo, for any additional apps you might need https://kaosx.us/packages/packages.php?sortby=name&sordir=asc&repo=kde-next
- Do install croeso6 to have a GUI for plasma settings, so far systemsettings6 is not usable
Issue with crashing systemsettings is fixed, installing Croeso no longer a strict necessity.
Now it is time to reboot, GUI won't work for this, so just run run
If you should run into any issues, it is easy to revert back to Plasma 5, just remove kf6 with -Rncs and install kdeplasma5, this can always be done in tty.
