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

sudo do-release-upgrade

which will try one more time to do the upgrade.

Please report your progress to us.
