[Bug 1366697] Re: Cannot dist-upgrade, mirror incomplete?

[era]

Additionally, https://launchpad.net/ubuntu/+archivemirrors should
monitor each of these addresses -- not just archive.canonical.com (which
is missing from the list, too) but each IP address it can resolve to.

era at lvcid:~$ host archive.canonical.com
archive.canonical.com has address 91.189.92.191
archive.canonical.com has address 91.189.92.150
archive.canonical.com has IPv6 address 2001:67c:1360:8c01::16
archive.canonical.com has IPv6 address 2001:67c:1360:8c01::1b

Title:
  Cannot dist-upgrade, mirror incomplete?

Status in “ubuntu-release-upgrader” package in Ubuntu:
  New

Bug description:
  The Update Manager in my 12.04 offers a dist-upgrade to 14.04 but it
  cannot be completed.

  """

  The IP address 91.189.92.191 resolves to sadalbari.canonical.com and
  indeed, http://sadalbari.canonical.com/dists/ does not contain the
  trusty-updates and trusty-security directories (and trusty-proposed
  looks fairly old, January 2014). I observed the same problem with
  kudan.canonical.com earlier today.

  $ lsb_release -a
  No LSB modules are available.
  Distributor ID: Ubuntu
  Description:    Ubuntu 12.04.5 LTS
  Release:        12.04
  Codename:       precise

  Sorry for not being able to figure out which package to report this
  problem against. I found something called "ubuntu-release-upgrader"
  but I do not have a package with that name.

  What I expect to happen:

  (a) If a mirror is incomplete or otherwise inconvenient, there should be an option to choose a different mirror
  (b) kudan.canonical.com and sadalbari.canonical.com need to be synced so that they offer the correct files and do not prevent upgrades until (a) is fixed.

  What actually happens:

  The upgrade is stopped, and changed settings are changed back to
  12.04.
