---------------
update-notifier (3.192.27) focal; urgency=medium

  * Notify user about stale updates information in motd (LP: #1842159)
  * Make /var/lib/update-notifier/updates-available world-readable
    (LP: #1844704)
  * data/update-motd-hwe-eol: Run as a regular user without printing errors
    (LP: #185527)
  * data/update-motd-hwe-eol: Shortcut script when running in a container.
    There is no point in checking the HWE stack in a container since upgrading
    it would not affect the host system. (LP: #1855290)

    a regular user (LP: #185527)

Title:
  Don't run /usr/lib/update-notifier/update-motd-hwe-eol in containers

Status in update-notifier package in Ubuntu:
  Fix Released

Bug description:
  [Impact]

   * Information of HWE kernels are shown in containers despite this information is useless most of the time since containers use the host systems' kernels.
   * The check for HWE kernels is noticably slow OTOH, taking around 0.2s on my intel i5 laptop.

  [Test Case]

   * Run the script in a container to see it being shortcut:
     $ bash -x /usr/lib/update-notifier/update-motd-hwe-eol
     + '[' '' = --force ']'
     + type systemd-detect-virt
     + systemd-detect-virt -q -c
     + exit
   * Run the script in a VM of without virtualization to see it still taking long time to execute:
    
      $ time /usr/lib/update-notifier/update-motd-hwe-eol

      real	0m0.241s
      user	0m0.170s
      sys 	0m0.073s

  [Regression Potential]

   * The fix is very simple there is no expected regression.
