[Bug 947664] Re: Unpacking linux-headers unbelievably slow in Lubuntu Precise (Beta 1)

[Raphaël Hertzog]

Well, you should definitely give more information about your
configuration.

What filesystem are you using ?

Is it significantly faster if you use dpkg's --force-unsafe-io ?

What's the process state in the "ps" output ?

Title:
  Unpacking linux-headers unbelievably slow in Lubuntu Precise (Beta 1)

Status in “dpkg” package in Ubuntu:
  New

Bug description:
  The below is an example line in an apt-get dist-upgrade which seems to
  take 30 minutes or more on a 2.1GHz CPU (one core of a quad core
  through Virtualbox). I've been looking at it for ages, and even had
  time to log in here and file the bug  - the line is still 'hung'.

  Unpacking linux-headers-3.2.0-18 (from .../linux-
  headers-3.2.0-18_3.2.0-18.28_all.deb)

  Can anyone explain this, or is it a bug in the configuration of
  Lubuntu, Apt-get or something. I read that there was a similarly
  behaving bug to do with dpkg using paranoid file synchronization but
  this length of delay is frankly a bit crazy.
