20.10: package qgis cannot be installed from ubuntu repo

[DarkTrick]

After qgis was uninstalled during the upgrade 19.10 -> 20.04 ( see https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1889030 ) I tried to reinstall it with `sudo apt-get install qgis` from ubuntu repos (not qgis repos).

The following is the output of apt-get:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

I'm not sure, if this is a problem caused by the upgrade. All the "Depends" look to me like a general "package dependencies are not properly configured" problem.

Sounds like the upgrade process destroyed something.

edit:
Installing qgis with qgis-repos enabled (https://qgis.org/ubuntu-ltr and https://qgis.org/ubuntu ) worked. So I guess something within the package inside ubuntu repos is broken.
