  1. – instead of –

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

  2. Could be done this way, too:

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

  3. Or you can just do
    sudo apt-get install –reinstall ubuntu-extras-keyring

  4. 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.

  8. Okay I’m gonna pull my hair out!…Love Ubuntu but I cannot update repositories!!! I have tried all the tips on this forum and all i get is:

    W: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/maverick/Release.gpg Something wicked happened resolving ‘us.archive.ubuntu.com:http’ (-5 – No address associated with hostname)

    W: Failed to fetch http://archive.canonical.com/ubuntu/dists/maverick/Release.gpg Something wicked happened resolving ‘archive.canonical.com:http’ (-5 – No address associated with hostname)

    W: Failed to fetch http://www.openprinting.org/download/printdriver/debian/dists/lsb3.2/Release.gpg Something wicked happened resolving ‘www.openprinting.org:http’ (-5 – No address associated with hostname)

    E: Some index files failed to download, they have been ignored, or old ones used instead.

  9. Proxy issues stopped “apt-key adv….”

    sudo apt-get install –reinstall ubuntu-extras-keyring

    …worked with proxy env vars set
