Come ripristinare sources.list?

[Sir Luke]

Come posso riprisitnare la versione originale di sources.list?
Perchè ho aggiunto un altro indirizzo ma aggiornando mi da questo errore:

W: Errore GPG: http://packages.medibuntu.org jaunty Release: Le seguenti firme non sono state verificate perché la chiave pubblica non è disponibile: NO_PUBKEY 2EBC26B60C5A2783

se vuoi tenere quel repo dai in terminale

Codice: Seleziona tutto

gpg --keyserver keyserver.ubuntu.com --recv 2EBC26B60C5A2783

e poi

Codice: Seleziona tutto

gpg --export -a 0C5A2783 | sudo apt-key add -

e dovrebbe darti ok

se lo vuoi togliere

Codice: Seleziona tutto

sudo gedit /etc/apt/sources.list

ti si apre il file, in basso elimini o commenti la riga mettendoci avanti #, salvi e chiudi

in entrambi i casi poi dai

Codice: Seleziona tutto

sudo apt-get update
