Oh I see. You are using Debian repositories. Unfortunately, Debian repos do not play nice with Ubuntu and are generally rejected. Remove the repository.

Also, you want Opera it seems. Download it here.

As for adding the public keys, you can import the keys with this command:

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 9D1A0061  06899068  4827A579

Perfect!

Where did you get those numbers at the end of the command?

The numbers are present in error messages stating that the public key is unavailable. Only the last 8 digits of the alphanumeric code are required, although you can enter the entire string.
