[Bug 1925519] [NEW] sudo do-release-upgrade -d -f DistUpgradeViewGtk3 failed early

[Michael Arlt]

Public bug reported:

There are no ppa's installed.
It was a new 20.10 installation a few days ago.

In an early phase I get this message (translated from German):

Could not determine which system updates are available

An unsolvable problem occurred during the system update calculation.

 It was probably caused by:
 * Unofficial software packages that are not provided by Ubuntu.
Please use the tool "ppa-purge" from the ppa-purge-
package to remove software from a Launchpad PPA and try to
try the system update again.

If none of these apply, please report the bug using the command 'ubuntu-
bug ubuntu-release-upgrader-core' in a terminal. If you want to
investigate this yourself, see the log files at "/var/log/dist-upgrade"
for system upgrade details. In particular, look at "main.log" and
"apt.log".
