Looks like a PPA you are using is not compatible with the new version.

If you are using the software updater to do the upgrade (on desktop ubuntu) then it should guide you through what to do when you encounter this eg ppa-purge, not just by removing the ppa or packages.

It's generally recommended to remove software from PPAs prior to an upgrade, or at the minimum, verify with the PPA maintainer whether it is compatible with the new ubuntu version.
