How to restore Ubuntu’s APT sources.list

If you have, for whatever reason, destroyed your local /etc/apt/sources.list file which Ubuntu uses for packages updates, here is a useful site which can regenerate it:

• country

• tick the first 12 checkboxes

Copy the result to your local file and run “apt-get update”.
