anch'io come molti altri utenti che leggo qui nel forum sono caduto nell'errore di "scaricamento delle informazioni del repository non riuscito".
Ho installato ubuntu 18.04.1 LTS su una partizione vuota del disco, e durante l'installazione ho spuntato l'opzione per scaricare software di terze parti.
Al primo riavvio del pc ho lanciato un aggiornamento da "Aggiornamenti softtware", ma l'aggiornamento è fallito con l'errore in oggetto.
Ho provato a eseguire il comando "sudo apt update" come consigliato negli altri post, e ho notato alcuni messaggi di errore:
