Ciao a tutti,

Ho installato ieri Ubuntu 15.10 sul mio vecchio pc ed è andato tutto liscio come l'olio.. ora però quando provo a scaricare software dal software center mi riporta questo errore:

Sapete dirmi di cosa si tratta? Suggerimenti?

Grazie in anticipo,
Matteo

Puoi installare versioni obsoleti ma non puoi aggiornarli e neanche installarci qualcosa - perché sono obsolete. Al minimo ci vuole la versione 16.04 LTS

Sapete dirmi di cosa si tratta? Suggerimenti?

le versioni quando terminano il supporto significa che i repository da dove vengono prelevati i pacchetti/aggiornamenti vengono spenti e quindi non esistono più e percià non si può installare/aggiornare niente. Devi installare una versione che sia supportata: 18.04 oppure 16.04.

Ah.. bel problema.. mi sapete consigliare una versione per il mio PC? È un hp h530.. l'unica modifica fatta è l'espansione di RAM a 3gb..

Grazie ancora!!

Prova una derivata tipo Xubuntu 18.04 lts oppure Lubuntu 18.04 lts...con 3 giga dovrebbero girare , e poi le lts sono supportate per qualche anno
