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

[Fake Name]

I can also confirm this issue.

I'm running vanilla Ubuntu Server 12.03 LTS in a Hyper-V VM.

It's been running for at least 15 minutes so far with no end in sight.

It's worth noting that I have no idea what the hold-up is. `iotop` isn't
showing any meaningful disk-activity, and the CPU isn't loaded at all.

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

Status in dpkg:
  New
Status in “dpkg” package in Ubuntu:
  Confirmed

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.
