I'm trying to install Ubuntu Tweak, for this I add a repository. sudo add-apt-repository ppa: tualatrix / ppa. Terminal gives the error:

Cannot add PPA: 'ppa:tualatrix/ppa'. ` `Please check that the PPA name or format is correct.

How can I install Ubuntu Tweak through the terminal?

    You need to export proxy server environment variables using:

     export http_proxy=http://username:password@host:port/ export https_proxy=https://username:password@host:port/

    and then tell sudo to use them using:

     sudo -E add-apt-repository ppa:webupd8team/y-ppa-manager

    or open the / etc / sudoers file (using sudo visudo) and add:

     Defaults env_keep="https_proxy"

    to the end of the file. Here is a link to the source.
