Po instalaci update a restaru nefunguje DNS

Zdravím,
včera se provedla instalace nového update a Turris chtěl provést restart. Tak jsem provedl a poté přestalo fungovat DNS. Níže zasílám log. V logu je vidět, že nemůže najít soubor root.key (can’t open ‘/etc/unbound/root.key’: No such file or directory). Kde mám ten soubor vzít, a jak je možné, že se ztratil? Děkuji za jakoukoliv odpověď

Provedl jsem factory reset a obnovu nastavení a nastal stejný problém. Tak jsem provedl znovu factory reset a vše nastavil znovu, vše funguje tak jak má. Také jsem měl rozhraní Luci v EN. Asi nějaká chyba po update na OS 3.6.

V konfiguraci je cesta /etc/root.keys ale skript pro unbound ji zřejmě nerespektuje. Defaultní resolver je kresd a tam to evidentně funguje (proto si toho asi zatím nikdo nevšiml).
