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?
