You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
dovecot-common : Depends: dovecot-core but it is not installed
dovecot-imapd : Depends: dovecot-core (= 1:2.0.19-0ubuntu2) but it is not installed
dovecot-pop3d : Depends: dovecot-core (= 1:2.0.19-0ubuntu2) but it is not installed
E: Unmet dependencies. Try using -f.

I then try apt-get -f install, and I get this:
root@otley:/home/otleylogic/domains/evgie.otleylogic.com/public_html# apt-get -f install
