TRYING TO INSTALL BRAVE°

[trinidad]

One of the browser updates (likely brave) is using a hook to the wrong version of python. "/usr/lib/cnf-update-db" is a python 3 script. I think jammy uses python 3.10 as default but that may have changed since its first release. Before messing with update-alternatives I would disable the brave ppa and maybe deadsnakes too and try running updates. Again the error is caused by a hook calling for a version of python that is not correctly enabled (linked).
Paste "/usr/lib/cnf-update-db" into google and read up on the problem.

One (or more) of the system files that the update script needs may have been lost.

Do you have any system backups made with the 'System Restore Utility' (Timeshift) that were made before the problem started ?

If so, this should allow you to restore the system files to the previous working state.

May be a problem with python loading a module which is very odd.
Was the system working and updating ok and then something changed ?
