My research lab has a super computer cluster, however they are all using Ubuntu 9.10. I need to install
nfs-kernel-server on the individual nodes so I can access to and process the files from a single node. But I am unable to
apt-get install nfs-kernel-server or
apt-get update. If I am understanding the situation correctly, it is because Ubuntu 9.10 is no longer being supported so there are no update list.
They question now is, should I try to update it to Ubuntu 14.04 LTS. The cluster does however, has some NFS and NIS set up. I can't afford to have them ruined. Will updating to 14.04 risk anything? I am fairly new to Linux so I don't know the details of how the cluster is set up.
