I moved over to the latest Kubuntu release and after successfully installing everything I removed some unwanted packages. However after a reboot I was stuck at the login screen showing an on screen keyboard and this error message:
The current theme cannot be loaded due to the errors below, please select another theme.
file:///usr/share/sddm//themes/breeze/Main.qml:No such file or directory
Long story short, the reason is the dependency management of some packages. I found that if you uninstall the calendar and the binary watch, virtually half of Kunbuntu is uninstalled, causing the system to fail.
Now I am struggling to find a way of reporting this. I am not sure if this is caused by KDE or if it is also a problem of the Ubuntu beneath it.
Any ideas how to tell the developers?
Had the exact same issue after uninstalling some basic programs through the UI.
Fixed it with
The first install made it possible to log on again and the second one fixed the rest.
You may use a virtual terminal to login (by pressing ctrl+alt+F1; if that doesn't work, try the other virtual terminals from ctrl+alt+F2 up to ctrl+alt+F6).
if you are still facing error while entering password try: go to the recovery option using any bootloader and then select any of the recovery version options and then select root: drop the root shell prompt and use the above two given codes..
