    For some reason I am getting an error message when I try to install opera-stable.

    Here is output from my console.

    I am not really too familiar with the way apt deals with the security keys but I wondered if it might be something wrong on the server.

    $ sudo apt update

      In a terminal and in that order

      wget https://deb.opera.com/archive.key
      sudo apt-key add archive.key
      sudo apt-get update 
      

      and you are done
