I am trying to link two ubuntu gutsy pcs using a HOWTO I found on this forum entitled NFS Server/Client. Both pcs are running kernel 2.6.22-14-generic. On the first pc I installed all went without any problem. However when I got to the second pc I ran into a problem. The following is the terminal log and at the end you can see the problem.

peter@test-pc:~$ sudo apt-get install nfs-kernel-server nfs-common portmap

How do I fix this
Thanks in anticipation.
