I can't install the ssh server so it's hard to copy and paste the results here, but I've also encountered this. Due to problems I'm having with a CD drive, I can't install edgy, but dapper installs fine. I think the CD drive isn't perfect.
Anyway, I'll type in what I can see. This is upgrading from a pristine dapper server install to edgy.
