    — instead of –

    gpg –keyserver keyserver.ubuntu.com –recv 3E5C1192
    gpg –export –armor 3E5C1192 | sudo apt-key add –
    sudo apt-get update

    Could be done this way, too:

    sudo apt-key adv –keyserver keyserver.ubuntu.com –recv 3E5C1192 && sudo apt-get update

    @dajomu – This worked for me, thanks!

  8. Arne says:

    For some reason this site shows a long dash (-) instead of the two ordinary ones (–) that should be used when typing these commands, so copy and paste does not work. You should check what settings or fonts or something you use here.

    See https://bugs.launchpad.net/ubuntu/+source/ubuntu-extras-keyring/+bug/650525 – the key for the repo seems to have changed to be one other than in the ubuntu-extras-keyring package. Bug report has the latest key in it.
