[Bug 1080631] [NEW] unattended-upgrades file descriptor leak

[Tim Cutts]

Public bug reported:

Debian #646620 affects Lucid.  The bug has been fixed in Precise, but
Lucid is still under support, and has the same problem; a zombie process
from unattended-upgrades prevents cron.daily from completing, and
everything gets a bit stuck.

The patch in Debian #646620 looks like a reasonable band-aid, but
unfortunately unattended-upgrades has changed a *lot* between its last
update in Lucid and what's currently going on in recent Debian and
Ubuntu releases.

Nevertheless, this is an important issue, because it seriously breaks
cron on Lucid machines.  I have to manually fix two or three production
machines a day here where run-parts has got stuck.

Any chance a similar workaround could be applied to the Lucid version?
I'm not sure my Python Fu is quite good enough to work out the
equivalent patch otherwise I'd have done it myself...

Thanks,

Tim
