[Bug 784112] Re: Doesn't allow upgrade to natty due to 'ubuntu-minimal missing' when it is present

[Wookey]

This bug still exists in natty-> oneiric transition. Having a local
archive means you can't upgrade with update-manager and you get a very
mysterious message about it. This is update-manager: 1:0.150.5

** Changed in: update-manager (Ubuntu)
       Status: Invalid => Confirmed
