I'm more or less as good a sysadmin as my serverfault rep mirrors. I have to upgrade a Debian (lenny) server with Plesk control panel. Plesk is supposed to manage that but the upgrade over the control panel doesn't work and I read and hear that this is often the case.
So I have to do it manually and now I'm running into seemingly circular dependency problems...
I get a lot of messages like this:
psa-updates depends on sw-cp-server (>= 1.0-6); however: Package sw-cp-server is not configured yet. dpkg: error processing psa-updates (--configure): dependency problems - leaving unconfigured
My sources.list is up to date and working,
apt-get clean and
apt-get update works fine and completes without errors.
What are the correct ways of solving such problems?
