Ubuntu

I could not upgrade to 20.04 from 18.04"an unresolvable problem occurred while calculating the upgrade".

Asked by Abdullahi Makama

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'.

How can I resolve this upgrade issue that appears not to have a cause?

Is their enough free space on your Hard drive to accomplish the upgrade?
