release-upgrade from apt-mirror fails

[lykwydchykyn]

I have a local apt-mirror on my network that I use to upgrade my Ubuntu and Debian systems; works great, had it for years, used it to do release upgrades in the past.

This time I'm trying to upgrade a fairly recently-installed 64-bit Lucid kubuntu machine to Maverick. When I try, I get this error:



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.


Anyone know the proper way to do this?

Ok, looking at the logs it seems to be rejecting my sources.list entries for the main apt mirror and commenting them out. How do I get it to accept these?
