- Salvare il tutto e chiudere l'editor di testo

- Scaricare le chiave gpg per i repository

wget -q http://medibuntu.sos-sts.com/repo/medibuntu-key.gpg -O- | sudo apt-key add -

wget http://download.tuxfamily.org/3v1deb/DD800CD9.gpg -O- | sudo apt-key add -

- Adesso dovremo aggiornare l'intero sistema con questi comandi

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

Fatto tutto quello che vi ho detto avremo finito di aggiornare la lista dei repository
