Kubuntu distro upgrade finalization failure - unconfigurable packages

After my recent upgrade attempt from 20 to 22 to 24 I got an installer error at the very end of the process (22 to 24) and now I'm left with several packages which were not configured normally. After spending several days trying to figure it out I gave up and asking for more or less step by step instructions on what to try to fix the issues. The sudo dpkg --configure -a output is as follows: Setting up memtest86+ (7.00-1build1) ... Sourcing file `/etc/default/grub' Generating grub configuration file ...

What would I need to do to configure the packages? I'm no Linux admin and can barely understand what they mean by those messages. Tried to look up 'general' unconfigured package issue fixes... But no suggested solution worked.
