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

[Martin Pitt]

Thanks Christian! Some remarks:

 - The introduction of data/get-motd-updates-available seems like an
unnecessary indirection to me. Instead of checking the executability of
that and run it, debian/90-updates-available could just directly do

  cat /var/lib/update-notifier/updates-available 2>/dev/null || true

or

  [ ! -r /var/lib/update-notifier/updates-available ] || cat /var/lib
/update-notifier/updates-available

if you prefer that. This would be simpler IMHO.

 - changelog should point out that data/update-motd-updates-available
now runs in the background, to avoid blocking "apt-get update"
unnecessarily long.

These are just nitpicks, this looks fine by and large. Thanks for
working on this!

Title:
  apt-check hangs, preventing login via SSH

Status in update-notifier package in Ubuntu:
  Confirmed

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.
