[Bug 1893974] Re: Distro upgrade bug3

[Laszlo Toth]

OK, thanks.

What are the mentioned PPAs & packages, applications? Which log file
contains the list?

Is it necessary to get rid of them?

What is the solution? Please provide a step-by-step description. Thanks.
Regards
L.

Title:
  Distro upgrade bug3

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

Bug description:
  HI All,
  1. lsb_release -rd
  Description:	Ubuntu 18.04.5 LTS
  Release:	18.04

  2.sudo apt-cache policy pkgname
  [sudo] password for laci: 
  N: Unable to locate package pkgname

  3. I expected a smart distro upgrade to 20.04

  
  4.During the upgrade process (18.04 LTS to 20.04 LTS)

  I got the following error message:

  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'

  Regarding security the availability is under real threat.
