Open een terminal. Geef eerst de volgende regel in (dat is om de sleutel te installeren van Medibuntu)
wget -q http://packages.medibuntu.org/medibuntu-key.gpg -O- | sudo apt-key add -
Vervolgens maak je een (nutteloze) backup van je huidige (vervuilde) sources.list...
sudo mv /etc/apt/sources.list /etc/qpt/sources.list.vervuild
Dan open je een tekstverwerker als root en je creƫert een volledig nieuwe sources.list (er zal een leeg bestandje openen, want het oude met die naam heb je net hernoemd...
gksu gedit /etc/apt/sources.list
Wachtwoord ingeven...
Nu kopieer en plak je de volgende tekst, opslaan en sluiten...
