Public bug reported:
subairkm@Subair-desktop:~$ lsb_release -rd
Description: Ubuntu 18.04.4 LTS
Release: 18.04
subairkm@Subair-desktop:~$ apt-cache policy pkgname
N: Unable to locate package pkgname
Expected: I want to upgrade from 18.04 to 20.04
Happened: An unresolvable problem occurred while calculating the
upgrade.
This was likely caused by:
* Unofficial software packages not provided by Ubuntu
Please use the tool 'ppa-purge' from the ppa-purge
package to remove software from a Launchpad PPA and
try the upgrade again.
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'.
