  <p>further while trying to install any application, i get the error, in this case for installing vim:-</p>
  
  <pre><code>Reading package lists... Done
  Building dependency tree       
  Reading state information... Done
  Package vim-gnome is not available, but is referred to by another package.
  This may mean that the package is missing, has been obsoleted, or
  is only available from another source
  
  E: Package 'vim-gnome' has no installation candidate
