updates-available is inaccurate

[Dustin Kirkland ]

Binary package hint: byobu

Byobu's updates_available is inaccurate, particularly immediately following an apt install or update. Previously we were relying on update-notifier, but the api has changed there.

We should fix byobu's updates_available mechanism to be more accurate to the present state of the system, and avoid unnecessary work. We can look at the timestamp on /var/lib/apt, and trigger background updates (writing those cache) only when /var/lib/apt is newer than our cache file.

This bug was fixed in the package byobu - 2.31-0ubuntu1

  * bin/updates-available, profiles/common:
    - reworked to be far more efficient, and accurate, LP: #427373
    - look at the timestamp on /var/lib/apt, and only update cache
      if /var/lib/apt has been touched since the cache
    - in particular, these changes fix a bug when the user does an
      apt-get install or upgrade, and changes to the update status
      are not update for up to an hour later; with these fixes, it's
      nearly immediate
    - and now that updates_available is trivial (in most cases), we
      can run it more frequently

  * Check that byobu-launcher exists before calling it (chroots use the same
    .profile as the main system but may not have byobu installed).
