[Bug 947664] [NEW] Apt-get unbelievably slow when unpacking in Lubuntu Precise (Beta 1)

[Cefn]

Public bug reported:

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.
