You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
ubuntu-release-upgrader-core : Depends: python3-distupgrade (= 1:18.04.34) but 1:18.04.29 is to be installed
ubuntu-release-upgrader-gtk : Depends: python3-distupgrade (= 1:18.04.34) but 1:18.04.29 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
