[Bug 1863449] Re: upgrade 19.04 to 19.10 - problem with repo - cannot upgrade

[Juhani Numminen]

Could you try again, but before the upgrade, disable disco-proposed by
adding a # character in the last line of /etc/apt/sources.list.

(Reason for my recommendation: The log files show problems with libc6
and libudev1, which have different versions in eoan-proposed than eoan.)

Title:
  upgrade 19.04 to 19.10 - problem with repo - cannot upgrade

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

Bug description:
  After type "update-manager"
  On stage "setting new software channels"
  This error is returned:

  "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'."

  But there are no repositories unofficials.
