ubuntu-release-upgrader can't upgrade my system from bionic to focal because of "held" packages, apt-mark showhold shows nothing.

I started upgrade process from update-manager (launched from gnome menu, without '-d' option), but got error:

Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade.

 If none of this applies, then please report this bug using the command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. If you want to investigate this yourself the log files in '/var/log/dist-upgrade' will contain details about the upgrade. Specifically, look at 'main.log' and 'apt.log'.
