Public bug reported:
Running Kubuntu 19.10, also on multiseat with LightDM
Package: ubuntu-release-upgrader-qt, version is 1:19.10.15.4. I had to submit
the package as ubuntu-release-upgrader, because apparently the QT version isn't
in vanilla Ubuntu's repositories.
I'm unable to upgrade to 20.04. The graphical upgrader (run from
Krunner) crashes after clicking "Upgrade".
Here is the output of "do-release-upgrade":
