I tried to upgrade my system via do-release-upgrade but some error occured. Now whatever I do (upgrade, dist-uprade, dpkg --configure -a, etc), I get many errors. For example:
root@hcompneu:~# apt-get dist-upgrade -f

E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

I have no idea how to resolve this. I tried many of the commands found here on Askubuntu for similar errors but none of them work.
Any suggestion would be welcome.
apt-mark showhold gives nothing.
I tried also apt, apt-get, aptitude, synaptics. All behave somewhat different but end up in errors.
