No results. Just those funny error messages. I copied everything from the
Terminal now.
What can be done ? In that time I would have done a new Ubuntu clean install
with deleting all the system folders and files except for what I have and
install without formatting.
What other alternatives are there except for reinstalling the system (done
really in 25 minutes) for the sake of one broken package that should not have
been installed after all and which interferes with the package manager ?
After a fresh install, there is 30-60 minutes of fun installing other
software, mainly from the repos.
