- Do this at your own risk. Modify the default Ubuntu sources.list only if you understand what you’re doing. Mixing repositories can break your system. For more information see the Ubuntu Command-line Repository guide.
-
- Create a backup of your current list of sources.
sudo cp -p /etc/apt/sources.list /etc/apt/sources.list_backup
Note: sudo – runs the command with root privileges. cp = copy. -p = prompt to overwrite if a file already exists.
-
- Edit the list of sources:
sudo nano /etc/apt/sources.list
-
- or using a graphical editor:
gksudo gedit /etc/apt/sources.list

- Note: To use your local mirror you can add “xx.” before archive.ubuntu.com, where xx = your country code.
