When I run apt-get update I get this error
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F6BC817356A3D45E
I can see for ubuntu this worked. I have not tried it because I am still abit afraid of doing something wrong.
I tried to search for "keyserver kali linux" and such, but nothing fit my problem except the one regarding ubuntu. Therefore I do want to try the command from the ubuntu forum.
I would also appreciate if an explenation on why it is a given that xxx keyserver is used and how I would have gone about figuring which keyserver is for my distro.
