The error message for this clean installation was the same as before. ahmett@nbs:~$ sudo apt-add-repository ppa:mosquitto-dev/mosquitto-ppa [sudo] password for ahmett: More info: https://launchpad.net/~mosquitto-dev/+archive/ubuntu/mosquitto-ppa Press [ENTER] to continue or Ctrl-c to cancel adding it.
