Thank you for taking the time to report this bug and helping to make
Ubuntu better.
I see a number of 3rd party packages, esp. from
https://launchpad.net/~oibaf/+ppa-packages
For best results with a release-upgrade, you should remove all 3rd party
packages (bringing your system back to a pure Ubuntu one, ie. no 3rd
party packages) then perform the upgrade. The tool ppa-purge can assist
with this.

release-upgrader/+bug/1922546/comments/2)
[The use of oibaf ppa] will prevent the upgrade as that PPA contains
package version numbers greater than the release to which you are
upgrading. You can revert the PPA by installing the ppa-purge package
from the official Ubuntu archive and then running 'sudo ppa-purge
ppa:oibaf/graphics-drivers'. After that you can try upgrading again and
if it still fails open a new bug report. Thanks and good luck!
