Chtěl jsem aby se bezpečnostní aktualizace sami instalovaly.
Povolil jsem to a po nějakých aktualizacích jsem znovu dal dialogové okno a volba tam najednou zmizela..

EDIT:
tejný problém mám v ubuntu mate 16.04.1
Nejdřív to šlo a po aktualizacích ta možnost zmizela
Podle návodu: wiki.ubuntu.cz/bezpečnost/automatické_bezpečnostní_aktualizace
/etc/apt/apt.conf.d/10periodic jsem měl na 1
Ale soubor /etc/apt/apt.conf.d/50unattended-upgrades jsem měl prázdný.
Krom toho že jsem neměl gedit takže jsem dal pluma to už je asi zastaralé celkově. Chtělo by to tu wiki aktualizovat..
