[Bug 2004139] [NEW] Could not calculate the upgrade

[Alireza Farahani]

Public bug reported:

When I perform do-release-upgrade I face the "Could not calculate the
upgrade" error. There are multiple broken packages in apt.log which I
think are the cause, but I don't know if it's safe to remove them.
