[Bug 1901978] [NEW] Does not want to update.

[valerie erasmus]

Public bug reported:

Update on my laptop starts then in the middle it says unable to upgrade
due to bugs exct.

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'.

As seen above I tried the ppa-purge and was even unable to download it
with sudo apt.
