  Invalid package information

  After updating your package information, the essential package 
  'ubuntu-minimal' could not be located. This may be because you have 
  no official mirrors listed in your software sources, or because of 
  excessive load on the mirror you are using. See /etc/apt/sources.list 
  for the current list of configured software sources. 
  In the case of an overloaded mirror, you may want to try the upgrade 
  again later.
