EDIT: UPDATE DEL 27 MAGGIO 2009: Ecco la lista aggiornata al 27 maggio 2009, con correzioni ed aggiunte.

Ecco la lista per i repository apt che uso da qualche mese, e che non ha creato alcun problema.
Attenzione ad usare il cervello e leggere quando si aggiorna o installa un software, un problema può essere dietro l’angolo.
Ricordatevi di aggiungere le chiavi gpg dei repository, operazione purtroppo un pò noiosa.
———
edit: Questo metodo, preso sempre da sourceslist, non fa altro che leggere il file /etc/apt/sources.list e importare le chiavi relative a tutti i repository ivi presenti. Basta immetere da konsole il codice seguente:

for i in $(grep -o -E “http.*.(gpg|asc|key)” /etc/apt/sources.list); do echo -n “$i “; wget $i -q -O – | sudo apt-key add -; done; keylist=”"; for key in $(grep -o “[A-Fa-f0-9]{8}” /etc/apt/sources.list); do if [ -z "$(echo "$keylist"|grep "$key")" ]; then keylist=”$keylist $key”; gpg –keyserver subkeys.pgp.net –recv $key && gpg –export –armor $key | sudo apt-key add -; fi; done;
——–

I repository contrassegnati da “********” sono presi da sourceslist.netsons.org
