That's a really tough question, probably the only way to know would be to run
apt-get install likewise-open openssh-server and see what apt is tripping over when you tell it you want both of them. Are you actually running Maverick? (Installed fresh or
apt-get dist-upgrade from a previous version) If you just updated apt's sources but never actually upgraded everything, then installing likewise-open might have pulled in a kerberos or openssl library that an older openssh-server wasn't compatible with, in which case installing openssh-server again would get Maverick's openssh-server.
This is one of the things I like about the front ends (
dselect was great about this)... they usually explain WHY the choice you made has this outcome.
