Title:
  Default hostname needed for PowerPC

Status in “choose-mirror” package in Ubuntu:
  Fix Released

Bug description:
  This has been raised before, notably in this bug
  https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/756719 , but
  the fix released appears not to have solved the problem.  From the
  comments made in that bug, the problem is still in the alpha version
  of 12.04.

  There have been a number of PowerPC bugs raised against the Ubiquity
  package, such as,
  https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/875460 .
  These are against 11.10 and 12.04.

  All the bugs share a similar problem:

  The relevant log lines from UbiquitySyslog.txt, are:
   Nov 5 12:40:45 ubuntu choose-mirror[10217]: DEBUG: command: wget -q http://mirror/ubuntu-ports//dists/precise/Release -O - | grep -E '^(Suite|Codename):'
   Nov 5 12:40:45 ubuntu choose-mirror[10217]: WARNING **: mirror does not support the specified release (precise)]

  From looking at the code of choose-mirror where these debug lines are
  outputted, it appears the hostname is set to "mirror".  It should be
  set to "ports.ubuntu.com" I think.

  Poking around a bit, I've been trying to figure out where this comes
  from.  A lot of the code relating to the debian-installer I don't
  understand I'm afraid.  My best guess is the problem lies in the file:
  choose-mirror-bin.templates.http-in

  I think the hostname part of it should be ammened to something like
  this:

  Template: mirror/http/hostname
  Type: string
  Default: mirror
  Default[powerpc]: ports.ubuntu.com

  A similar alteration can be made to the file: choose-mirror-
  bin.templates.ftp.base-in

  From reading the Apple forum today it appears the alternate CD is also
  still affected by the problem:
  http://ubuntuforums.org/showthread.php?t=1912207

  I don't know if it is significant, but all the bug reports are from
  people outside the UK.  A UK user a few days ago said they did not get
  a mirror error with the 12.04 live CD, but the live/desktop installer
  did freeze on them.

  Anyway, I hope this helps!  Thanks for taking the time to read this!
