10.10 to 11.04 Upgrade Fails with "ubuntu-minimal" cannot be found error

[durrell]

I've seen this happening to others, but can't find the original bug report I saw. From what I can tell I'm getting the error because I am using a local mirror, as others have successfully updated using "official" mirrors.

What would cause the installer to differentiate between a local and an official mirror? I'm pulling everything anl.gov has for Lucid, Maverick, and Natty, and had no problems using the local mirror to dist-upgrade from 10.04 to 10.10.

The exact error is:



After your package information was updated the essential package 'ubuntu-minimal' can not be found anymore.
This indicates a serious error, please report this bug against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bug report.


main.log from /var/log/dist-upgrade:

from synaptic config repo, choose "main server" to download, then clean the sources:

sudo rm /var/cache/apt/archives/*
(ignore the complain)

then update

note: of course disable all non genuine natty repo like ppa first

Well that's kind of the question. Why should I need to do that when my mirror is working fine?

Thanks for the response.

I second that. Same here, local mirror and I must use an official mirror for a dist-upgrade

Thanks
