As I was looking for a way to open ports (and keep them open) I read that ssh server is not installed by default. So I tried to apt-get it with the following results:

bmike1@Michaels-PC:~$ sudo apt-get install openssh-server
[sudo] password for bmike1:
Reading package lists... Done

openssh-server is already the newest version.
openssh-server set to manually installed.
0 upgraded, 0 newly installed, 0 to remove and 10 not upgraded.
5 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.
Do you want to continue [Y/n]? n
Abort.
bmike1@Michaels-PC:~$

So it seems that it is installed  but what is this, 'openssh-server set to manually installed.' Does this mean thae packages are there but it isn't installed? How do I install it?
