I finally decided to upgrade to Ubuntu 20.04 from 18.04 today after waiting to ensure there was compatibility with some programs I use my Ubuntu machine for. While running the upgrade today I got an error saying:
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'."
I've searched tirelessly through forums and anywhere I could find help with this subject, and tried a few solutions I found, but none seem to fit my circumstance. I've disabled all unofficial and third-party packages that I know of. I wanted to see if someone could take a look at my logs from /var/log/dist-upgrade/ and help me with a solution to this error. I would really appreciate any help anyone could give me.
