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

Fri Sep 19 14:08:47 UTC 2014

appears that i have run into the same bug while upgrading my system from
1204 to 14041.

my apt-term.log file seems to match exactly.

i've grabbed ps output and a few other things from the hung process,
since @lkalev mentioned that he hadn't grabbed them before killing the
process.

the wchan (from /proc) is actually futex_wait_queue_me, though i'm not
sure how helpful that will be for finding the offending bug.

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:
