I'm following the instructions on ubuntuguide.org for upgrading my Dapper Server to an Edgy Server. (There were no guides here, so I had to take the next best route!) I'd initially followed the "Perfect Install" walkthrough on here for getting Dapper set up. I took the advice at ubuntuguide.org for upgrading to Edgy - changed the sources and used aptitude dist-upgrade. It seems to be upgrading everything, not just the OS. So far it's asked me lots of questions about keeping my old conf files or replacing them with the new ones. I had questions about this on proftpd, mime and mysql server. Probably at least one more that I'm forgetting now. The other issue is with configuring courier. It keeps hanging on upgrading courier. Should I be concerned with either of these issues and if so, what steps will I need to take? Also, should I anticipate any problems with ISPConfig once it's done? (I'm not too worried about courier. So far I've been able to send mail out but I've not been able to configure my MX pointers correctly through Dyndns to get my incoming mailserver accepting anything. Courier is the least of my problems -- this is a locally hosted testing server only.) Bear in mind, I just set up the Dapper server a few weeks back, so I've barely broken it in and have never had to restart it. EDIT post upgrade: OK, nearly everything came out alright by always choosing "no" if it asked me about replacing config files. However, at the very end, it spat out the following: Code: Errors were encountered while processing: courier-authlib-userdb courier-base courier-authdaemon courier-imap courier-ssl courier-pop courier-pop-ssl courier-imap-ssl Suggestions as to what to do about this?
