It looks like you have a bad ppa. Go to menu, Administration , software sources and then to other tab. uncheck all your ppa's and try

Code: Select all

sudo apt update

again.
if that works. try the upgrade manager again. if software Sources will not open from menu go to a terminal and type

Code: Select all

pkexec mintsources

post any error message you get.

Sembra che tu abbia un ppa cattivo. Vai al menu, Amministrazione, fonti software e poi in altra scheda. deseleziona tutti i tuoi ppa e prova di nuovo [codice] sudo apt update [/ code].
se funziona. provare di nuovo il gestore aggiornamenti. se il software Sorgenti non si apre dal menu, vai a un terminale e digita [codice] mintsources pkexec [/ code]
pubblica qualsiasi messaggio di errore che ricevi.

Thanks for the help!

I don't think i have a bad ppa, ithink the error is given by a official mirror "evowise"

Code: Select all

Errore:7 http://mirrors.evowise.com/linuxmint/packages tara Release.gpg
  Le seguenti firme non erano valide: BADSIG A6616109451BBBF2 Linux Mint Repository Signing Key <root@linuxmint.com>

Anyway, i tried

Code: Select all

pkexec mintsources

and

Code: Select all

mosco@mint-PC ~ $ pkexec mintsources
