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

[RichardNeill]

This is really painful - although I don't experience complete hangs, I do experience 12-second+ delays while
the script "90-updates-available" grinds slowly though.  So login via SSH is unpleasantly slow. Furthermore, bash completion for tab completion on scp commands is also very slow.

The workaround is:   chmod -x /etc/update-motd.d/*

However, it seems to me that this should be a cron-job which runs once
an hour (and @reboot). There's no need for it to happen at the precise
moment where I log in.

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.
