[Bug 1916805] [NEW] 18.04 to 20.04 upgrade failure

[Hugo Toonen]

Public bug reported:

A question in Nov 2020 appeared in http://answers.launchpad.net/ubuntu/
:

694046  not able to upgrade to 20.04 fm 18.04 Could not calculate the
upgrade An unresolvable problem occurred while calculating the upgrade.

I have the same problem for months now. His question was not resolved.
Hope the bug is fixed because in April 2023, 18.04 will be obsolete.
Might need to buy a new computer and OS.

Both of us may not the most computer literate. Or haven't been answered.

Thank you.
