E: Some index files failed to download. They have been ignored, or old ones used instead.
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

Is it a desktop or server edition? If desktop, try the following:

  • open System settings and click Software & Updates;
  • click the "Download from" field and select "Main server";
  • launch Software updater (or run sudo apt-get update, then sudo apt-get upgrade)
