In Ubuntu 11.10 un problema nella definizione dei sorgenti non consente di aggiornare ad ubuntu 12.04

Ci invii il contenuto di /etc/apt/sources.list da terminale digita:

gedit /etc/apt/sources.list

copia ed incolla il contenuto qui sotto...

Non puoi aggiornare 11.10 a 12.10 ma devi passare da 12.04

E' possibile aggiornare direttamente 10.04 a 12.04 senza passare dalle release intermedia (non e' il tuo caso).

Le righe che devi correggere sono queste

deb http://archive.ubuntu.com/ubuntu oniric main
deb-src http://archive.ubuntu.com/ubuntu oniric main

devi modificarle in (attento non e' oniric ma oneiric)

deb http://archive.ubuntu.com/ubuntu oneiric main
deb-src http://archive.ubuntu.com/ubuntu oneiric main

apri con il comando

gksudo gedit /etc/apt/sources.list

modifica, salva riprova a fare l' upgrade della release...

Ciao

Grazie per il suggerimento. Ritarderò a darti risposta perché sono fuori sede.

Dopo avre modificato i due ultimi oniric in oneiric non posso salvare perchè il pulsante salva è disabilitato.
Allora chiudo e sebbene viene richiesto non posso salvare per i seguenti motivi:
1)-"Il file è in modalità sola lettura tentare di sostituirlo con quello che si sta per salvare?"
Dopo il clic su salva, in alto appare una striscia rossa co su scritto
2)-"Impossibile salvare il file etc/apt/sources.list
permessi insufficienti assicurarsi di avere digitato correttamente la posizione e riprovare
Controllo bene, del resto si tratta solo di inserire due "e", provo più volte senza risultato.
Immagino che tutto dipenda dal fatto che il file è di sola lettura. Incollo di seguti il file modificato che non posso salvare
Grazie e ciao

You say: "this question was expired because it remained in the 'Open' state
without activity for the last 15 days." But I am still waiting for your answer.

Assicurati di scrivere

gksudo gedit /etc/apt/sources.list
