How To Upgrade Ubuntu 9.04 (Jaunty Jackalope) To 9.10 (Karmic Koala)

[melwood]

The courrier-base package and all dependencies are not updating because of the bug in the courier-base package also mentioned in the "Perfect Server" howto.

You get the following error:

update-alternatives: error: alternative link /usr/share/man/man5/maildir.5.gz is already managed by maildir.5.gz.

Any idea what to do?

Have you tried this before the upgrade?

update-alternatives --remove-all maildir.5
update-alternatives --remove-all maildirquota.7

Yes, it's not working:

bla@blu:/home/bla# update-alternatives --remove-all maildir.5
update-alternatives: error: no alternatives for maildir.5.
bla@blu:/home/bla# update-alternatives --remove-all maildirquota.7
update-alternatives: error: no alternatives for maildirquota.7.

Hm, maybe the best is to completely remove all Courier packages before the upgrade, then do the upgrad and install Courier again afterwards. Instead of removing Courier you could also try this with maildrop.

Any change I'll break my mail configuration or delete any mail accounst when I do this?

No, this will just remove the Courier packages.

Thanks for the help!

aptitude remove maildrop
aptitude safe-upgrade
update-alternatives --remove-all maildir.5
update-alternatives --remove-all maildirquota.7
aptitude install maildrop

did the trick. :-)
