[Bug 2083120] Re: Unable to upgrade to 24.04 on System76 Laptop

[Julian Andres Klode]

Closing this as systemd is installed from Pos!OS (in version
249.11-0ubuntu3.11pop0~1704473387~22.04~3ce38bf~dev), we cannot support
systems with core packages replaced by third-party repositories.

Title:
  Unable to upgrade to 24.04 on System76 Laptop

Status in ubuntu-release-upgrader package in Ubuntu:
  Invalid

Bug description:
  When I try to upgrade to 24.04 from 22.04 I receive the following
  error on the command line from do-release-upgrade (it was essentially
  the same error through the GUI). Note that the logs contain no obvious
  errors and the only PPA enabled and unpurged is the one from System76:

  Calculating the changes

  Could not calculate the upgrade

  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'.
