Upgrade partially failed 20.04 to 21.04

[Robbyx]

The problem is obviously connected with python3. How do I correct it? There is no code options showing in firefox, hence the pure listing below;

[Robbyx]

As the error messages first appeared during the upgrade to 21.04, as I have gone back to 20.04 what should I now check?

[Impavidus]

It complains that the packages gdebi-core and gdebi are not installed. Have you made sure they're actually installed?

There's also a syntax warning (just a warning) from a python script belonging to bleachbit, which is apparently triggered when python is upgraded. That might be an issue too.

Generally, don't spend too much time troubleshooting failed release upgrades. Just fresh install.
