It took a virtual machine more than half an hour to finish it.

Ubuntu 12.04.2

Title:
  spends 10+ minutes deduplicating Package lists

Status in “net-retriever” package in Ubuntu:
  Confirmed

Bug description:
  At some point after Lucid's initial release, the ubuntu alternate
  installer seems to stall for a very long time (10+ minutes) before the
  partitioning menu comes up. I don't think it was happening for the
  first year or so after Lucid's release, but I'm not real clear on when
  it started happening (it was only recently brought to my attention).

  I think it is happening in /usr/lib/debian-installer/net-retriever's deduplicate function...
  When it is stalled out, it keeps adding content to /tmp/net-retriever-NNNN-deduplicate/, eventually it moves on, but it takes forever. The speed of the install machine doesn't appear to matter much.
  There's nothing obvious in the log as to why it's stalling at that point...

  I thought it might be some issue with our preseeding, but it appears
  to happen on an install without preseeding as well.

  Newer versions of Ubuntu (at least Xubuntu 12.04) don't seem to
  experience this problem, as far as I can tell.

  We're using the netboot installer, apparently last updated on
  2011-04-29:

  2011-04-29 03:32:27-07:00 checking for updates: http://us.archive.ubuntu.com/ubuntu/dists/lucid/main/installer-i386/current/images/netboot/netboot.tar.gz
  2011-04-29 03:33:13-07:00 updated: /var/lib/tftpboot/ubuntu-installer/lucid.i386.netboot.tar.gz

  though as far as i can tell, that file hasn't been updated on the
  mirrors since 2010-04-25.

  live well,
