I'm sorry to post this question again. I posted it before but got absolutely no replies. I know how to add repositories to the Software Sources list in Mint now. However, I'm still stuck as to how to add the public keys.
Can anybody help me out on this one, point me towards a thread or something? I was only able to find one thread about it and it was confusing since the posters were arguing between them about something not even related to the subject:
Thanks for any help.
