do-release-upgrade fails with "Could not calculate the upgrade"

Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade.

 This can be caused by:
 * Upgrading to a pre-release version of Ubuntu
 * Running the current pre-release version of Ubuntu
 * Unofficial software packages not provided by Ubuntu

If none of this applies, then please report this bug using the command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal.

Reviewing the files from your upgrade attempt you seem to have enabled the xorg-edgers-ppa. This will prevent the upgrade as that PPA contains different versions of packages essential to Ubuntu. The page, https://launchpad.net/~xorg-edgers/+archive/ppa, contains details on to how to revert to the official Xorg packages.

[Rich Stillman (mobiguy)]

I followed instructions and removed all ppas using add-apt-repository --remove followed by ppa-purge. Nothing changed in the flow of do-release-upgrade.

[Brian Murray (brian-murray)]

ppa-purge only works when the PPA is enabled so by using add-apt-repository --remove first, you've prevented ppa-purge from doing anything.

[Rich Stillman (mobiguy)]

I added the PPA packages back in, reinstalled the related software, and removed them with ppa-purge. Followed that with apt update, autoremove and a necessary reboot. After all that, I got the same "unresolvable problem" error when I tried to do-release-upgrade.

[Brian Murray (brian-murray)]

Please submit a new bug using 'ubuntu-bug ubuntu-release-upgrader' as that will add log files which I can examine to help sort out the situation.

Thanks for checking. I have submitted the bug report. It is bug #1902767.
