Yesterday I tried to upgrade my PC with Kubuntu to 18.10. During the installation process there occurred an error because of breeze (probably).
Now I am stuck with 18.04 and can't execute apt upgrade or do-release-upgrade etc. It always shows the following error message:
The following packages have unmet dependencies:
breeze : Depends: breeze-cursor-theme (4:5.12.6-0ubuntu0.1) but 4:5.13.5-0ubuntu2 is to be installed
...
plasma-integration : Depends: breeze (>= 4:5.13) but 4:5.12.6-0-ubuntu0.1 is to be installed
Running apt --fix-broken install or purging and reinstalling breeze couldn't fix the issue...
Edit - output of apt-cache policy breeze:
