[Bug 1365939] Re: package man-db 2.6.7.1-1 trigger froze during dist upgrade from 12.04.

[Jeremy Schneider]

just in the off chance off chance that someone is watching their email
today and has suggestions for additional diagnostics info, i will leave
my system hung for a few hours before i finish the upgrade.  let me know
if you have any requests.

based on @lkalev's original bug report, and also on
http://askubuntu.com/questions/453831/help-online-upgrade-
from-12-04-to-14-04-stuck which appears to be describing the same
problem, it seems that the workaround is to just kill the "perl
frontend" process and the installation process should restart itself and
complete successfully.  i'll try this later today.

this might be a bug in the frontend upgrade script rather than man-db.
it seems that dpkg properly failed the man-db upgrade, but the frontend
program got hung after dpkg failed.

Title:
  package man-db 2.6.7.1-1 trigger froze during dist upgrade from 12.04.

Status in “man-db” package in Ubuntu:
  Confirmed

Bug description:
  While upgrading Ubuntu Studio from 12.04 to 14.04.1, the man-db post-
  install trigger froze and I had to kill it. After that the upgrade
  proceeded normally (I ran the man-db update manually after that, just
  in case).

  The process that I killed was blocked on 'futex_wait' (I believe it
  was a Perl script, but I forgot to save the line from the 'ps'
  output).

  Here is the relevant part of the /var/log/dist-upgrade/apt-term.log
  file:
