Building dependency tree... Done
You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
  alternc: Depends: apache but it is not going to be installed
           Depends: courier-ssl but it is not going to be installed
           Depends: courier-imap-ssl but it is not going to be installed
           Depends: courier-pop-ssl but it is not going to be installed
           Depends: proftpd-mysql but it is not going to be installed
           Depends: bind9 but it is not going to be installed
           Depends: libapache-mod-gzip but it is not going to be installed
           Depends: rsync but it is not going to be installed
           Depends: quota but it is not going to be installed
           Depends: courier-authmysql but it is not installable
           Depends: perl-suid but it is not going to be installed
           Depends: postfix-mysql but it is not going to be installed
