Ubuntu – Cannot add PPA. Please check that the PPA name or format is correct

ppa

Internet connection is working.

apt-get is working.

Trying to add ppa:cooperjona/lightread but an error has raised:

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

I supposed there is an error in writing or in the PPA.

I tried also the 'ppa:tombeckmann/ppa' but with same error.

  • Open Terminal and run the command

    sudo apt-get install --reinstall ca-certificates
    

    It may work, but if doesn't then run

    sudo -E add-apt-repository ppa:ppaname/ppa
    

    instead of sudo add-apt-repository ppa:ppaname/ppa
