I am experiencing issues AFTER a seemingly perfect installation via USB with connected internet.
As soon as installation completes system prompts for reboot. No issues exist.
After rebooting and logging in, I proceed to run "sudo apt update && sudo apt upgrade" from the Konsole to fully update the system.
Once updates have been downloaded and installed, it's time to reboot to affect the changes.
This is where my issues begin.
The system reboots and immediately presents me with an on-screen keyboard, behind which is an unfamiliar login screen with the message:
"The current theme cannot be loaded due to the errors below, please select another theme."
"file:///usr/share/sddm/themes/ubuntu-theme/Main.qml:204:17: Cannot assign to non-existent property "actionItemsVisible""

I have tried more than twice reinstalling with identical results.
Downloaded a fresh ISO and after validating the checksum wrote the ISO to a USB.
Again a fresh installation produced the same result. No Joy!
Booted in recovery mode and tried:
sudo apt-get install sddm-theme-breeze
sudo apt-get install --reinstall plasma-desktop
No effect.
Disabled updates for everything "plasma and breeze" related. Issue persists.
Installed xbuntu desktop "sudo apt install xubuntu-desktop" and everything tested worked fine. Except it's not the "look or feel" I seek.
Finally disabled all but security updates after the last installation..
As long as general updates are disabled the system works great. Security updates are enabled and don't cause any issue after rebooting.
I would like to resolve this issue correctly and completely so I can have a fully patched, working OS. Love Ubuntu Studio! Been using it for years!
Any advice would be greatly appreciated.
