[Bug 525674] Re: apt-check hangs, preventing login via SSH

[Launchpad Bug Tracker]

This bug was fixed in the package update-notifier - 3.164

---------------
update-notifier (3.164) xenial; urgency=medium

  * debian/90-updates-available
    - Now directly prints the cached info if available
      => avoid login stalls due to motd updates (LP: #525674)
    - Also fixes a former potential issue of existing but not readable cached
      info by changing the test from -e to -r
  * debian/99update-notifier:
    - Now additionally triggers the an asynchronous background update of the
      cached info via update-motd-updates-available hooking into
      APT::Update::Post-Invoke-Success.
  * data/update-motd-updates-available:
    - This now only contains the slow part of actually 'updating the cached
      info'.
    - It executes asynchronously to avoid stalling apt-get update.
    - The file is no more called by pam to avoid login stalls.
    - It also fixes an issue with concurrent updates clobbering the
      cached file via mv being atomic

Title:
  apt-check hangs, preventing login via SSH

Status in update-notifier package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: update-notifier

  While investigating protracted hangs in the remote login process, I
  noticed that apt-check is called to update the list of available
  updates and print the number of updatable packages in the MOTD. As it
  so happens, apt-check often hangs in mid-update, which effectively
  prevents remote login via SSH from taking place.
