    I failed to install indicator-brightness anyway.
    1) How can I clear indicator-brightness from my repository, as :

    I tried to add docker support with command :
    sudo vi /etc/apt/sources.list.d/docker.list
    Code (markup):
    New file docker.list was created.


    I deleted it manually , but I still got errors :

    
root@master-laptop:/etc/apt/sources.list.d# sudo add-apt-repository --remove ppa:indicator-brightnes
Cannot add PPA: 'ppa:~indicator-brightnes/ubuntu/ppa'.
ERROR: '~indicator-brightnes' user or team does not exist.
root@master-laptop:/etc/apt/sources.list.d# sudo apt-get update
