[Bug 773823] Re: fails to upgrade with non-official repositories

[Nathaniel W. Turner]

This worked with upgrades to the current LTS version (10.04). My
organization has a fairly large number of Ubuntu workstations running
the current LTS release, and we have a private mirror to speed up
updates and installs (and reduce the burden on the public mirrors).

I did a trial upgrade from 10.04 LTS to 12.04 LTS today to see if there
would be issues when it releases, and I ran into this regression. (All
private mirror sources get disabled without any option to rewrite.)

I suspect (but have not confirmed) that the issue may be related to the
automatic addition of /etc/apt/sources.list.d/prerequisites-
sources.list, which probably confuses the code that checks to see if you
have any valid official repositories enabled.

Perhaps the heuristic that is used to determine whether you have a
private mirror could be improved slightly?

It would be really awesome if this were fixed before the 12.04 LTS
release so that LTS -> LTS upgrades at large deployments with internal
mirrors do not all get bitten by this regression.

Title:
  fails to upgrade with non-official repositories

Status in “update-manager” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: update-manager

  I have my /etc/apt/sources.list point to my approx mirror, so I don't
  have to download copies of every file for every computer I upgrade.
  update-manager considers all these entries as 3rd party sources and
  disables them all, and then complains it can't find ubuntu-minimal.

  Sometimes it will ask me if I want to rewrite maverick to natty - this
  always use to happen prior to 11.04, but now it is very inconsistent.
  I can't see how to activate that part of the code. When it does ask
  me, everything works fine.
