Hello.
After today’s updates plasmashell is not loading anymore. Apps from previous session are loading, I can launch terminal via ctrl+alt+t but no network is available. Investigated some logs, it complains about new theme json format and unable loading qml due to some unexistent properties, which I have tried to remove from qml files but with no luck. Since network is not available, i cannot get any updates or search for solutions and writing this message from another PC. Any help is appreciated. Thank you!
System: UbuntuStudio 26.04 updaited daily. So the issue should be in updates since yesterday. Yesterday as I noticed plasma was updated, but today it loaded ok, then after updates and reboot it stopped working.
Do you know about Ubuntu Friendly Recovery?
At the Grub menu select Advanced Options for Ubuntu and then select a Linux kernel with recovery mode.
That will load Linux and present you with a Recovery Menu. Select Network. That will set up an internet connection using settings already in the OS.
Now you can select some of the other options. For example, Root will give you a root shell prompt where you can run apt update/apt upgrade. And other Linux commands. When you are finished type exit to return to the recovery menu.

Indeed I have used it. Upgraded everything including dist-upgrade since 4-th snapshot was released recently. Cleared ~/.config/session/* then deleted everything plasma related from ~/.config and whole ~/.cache contents. Run sudo apt install –reinstall ubuntustudio-desktop (already up to date). And still no desktop. Network is working, I can run apps with ctrl+F2, but no wallpapers and panels here. What logs can I share here to help solve the problem?
PS. Trying to switch nvidia drivers now and reinstall everything about plasma…
switched to nvidia-driver-580-open did not help.
Helped only
sudo apt install –reinstall plasma-*
Now it’s solved.
Not sure if it’s related, can’t confirm.
But today I have upgraded same Ubuntustudio 26.04 on laptop with same result. And same, reinstalling plasma-* packages fixed desktop.
People have reported that installing the package libqt6wlshellintegration6 fixes the broken panel issues. If that is the case, we will be looking at why Plasma builds did not automatically generate a depend on that.

I have had about a month old never updated nightly build clean install on laptop. So here is a test case. Install month old snapshot and do dist-upgrade.
