In general, when there is a problem upgrading, the first thing to try
in the commandline is
sudo apt-get install -f
The -f means fix.
If the report is that there is nothing more to download or fix, try:
sudo apt-get update && sudo apt-get dist-upgrade
which might help as well. "Dist-upgrade" will both upgrade any
packages needing upgrading, and also autoremove any no longer needed
One final command to try is
sudo dpkg -reconfigure -a
where -a means "all".
sudo dpkg --configure -a
will configure all unpacked but unconfigured packages if that is the problem.
Finally, you can once more run
which will try one more time to do the upgrade.
Please report your progress to us.
