Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

I followed the question (and the question inside posted by @retiredfeline ) from here: https://forum.kicad.info/t/broken-packages-on-ubuntu/48307
I tried to remove, install, update and upgrade the broken pakages but it did not help.
