[Debian-sf-users] Purging sourceforge

[John Smiths]

I'm trying to purging apache, postgresql, ldap, proftpd, php4 and sourceforge 
cause i've made a good mess with configuration files and i want to restart from 
the beginning.
But i can't get to remove sourceforge package cause it's searching for 
something i don't have anymore:

julio:/var/cache/apt/archives# dpkg --force-all --purge sourceforge 
(Reading database ... 51314 files and directories currently installed.)
Removing sourceforge ...
Restarting proftpd daemon... - No certificate files found!
done.
/usr/sbin/deluser: `sfftp' does not exist.

dpkg: error processing sourceforge (--purge):

Errors were encountered while processing:

Is there a way i can fix this things and get the sourceforge package removed?
Thank you for support.
