I am extremely new to Ubuntu and need to work on EdX platform. I need to install the NFS Client on Ubuntu 12.04 for the same. I used the following

stuti@stuti:/$ sudo apt-get install nfs-kernel-server

However this gives me an error as follows:

Reading package lists... Done

Reading state information... Done
The following extra packages will be installed:
nfs-common
The following NEW packages will be installed:
nfs-common nfs-kernel-server

I have tried

sudo apt-get autoremove nfs-kernel-server
sudo apt-get autoremove nfs-common

After these, I tried to install but I keep getting the same error. apt-get update or upgrade also do not help and give the same error.
I am clueless as to where can I find this missing file as stated in the output. I tried to google about this problem but none of the solutions I came across have helped or I have not been able to understand some of them.
Any help would really be appreciated. Thanks in advance for your time and attention.
