[Bug 960525] Re: aptitude -d Failed to write temporary StateFile /var/lib/apt/extended_states.tmp - also consumes CPU power and takes a while to finish the operation after download

Here's the strace output. I've compressed with "bzip2 -9".

Title:
  aptitude -d Failed to write temporary StateFile
  /var/lib/apt/extended_states.tmp - also consumes CPU power and takes a
  while to finish the operation after download

Status in “aptitude” package in Ubuntu:
  New

Bug description:
  If I use aptitude with the -d option it consumes a lot of CPU power and takes a while to finish
  (give me the prompt) after the download. Before aptitude give me back the prompt print the following
  error message:

  E: Failed to write temporary StateFile
  /var/lib/apt/extended_states.tmp

  Until today I haven't encountered with this phenomenon. So aptitude with the -d option worked well
  when Ubuntu 12.04 Beta1 released.

  Without the -d option everything is just fine.

  I've created a strace output with the following way:

  root at penge:~# strace -o aptitude.strace aptitude -d install vim
  The following NEW packages will be installed:
    vim vim-runtime{a}
  0 packages upgraded, 2 newly installed, 0 to remove and 0 not upgraded.
  Need to get 6,872 kB of archives. After unpacking 24.8 MB will be used.

  Fetched 6,872 kB in 11s (610 kB/s)
  E: Failed to write temporary StateFile /var/lib/apt/extended_states.tmp

  I will try to upload the strace file later (48M without compression).

  Here's a typical top output when aptitude -d run after the donwload
  has been finished:

  The aptitude process state not always "S" it's sometimes "R".
