[Bug 1787622] Re: could not upgrade Kubuntu 16.04.5 LTS to 18.04.1

[Rolf Leggewie]

Andrea, thank you for reporting back.  The software triggering the bug
is the acng server running on 14.04.  That's from universe and thus no
longer supported.

Closing task as obsolete.  Please open a new bug ticket if you reproduce
the problem with a newer version of acng in the future.

** Changed in: apt-cacher-ng (Ubuntu)
       Status: New => Invalid

Title:
  could not upgrade Kubuntu 16.04.5 LTS to 18.04.1

Status in apt-cacher-ng package in Ubuntu:
  Invalid
Status in ubuntu-release-upgrader package in Ubuntu:
  Expired

Bug description:
  When the message appeared "A new version of Kubuntu is available" and
  I clicked on Upgrade, the upgrade tool window "release notes" opens,
  but a message immediately pops up stating that it cannot find release
  notes due to server overload.

  Running "do-release-upgrade -m desktop -f DistUpgradeViewKDE" as root
  has the same results.

  At home, I successfully upgraded a nearly identical Kubuntu 16.04.5
  LTS system to 18.04.1 with the same command.

  At work - it doesn't work. Only difference is, we're using an apt-
  cacher-ng proxy here (we manage several workstations). Here's the
  output of a few commands:
