I am trying to install gnome desktop from kubuntu. So I did this :
sudo apt-get install ubuntu-desktop It ran well but now I am getting this error:
sudeep@sudeep:~$ sudo apt-get install ubuntu-desktop Reading package lists... Done Building dependency tree Reading state information... Done ubuntu-desktop is already the newest version.
