I just had the same problem. I realized that this same output error happens because even though I have just uploaded my package (sources), it is still in queue for building, and while this is unfinished, if I try to add the repository with the command add-apt-repository, as it also tries to handle the signatures, it ultimately fails.
So, this is not actually a problem. My output: $ sudo add-apt-repository ppa:bruno-braga/termsaver [sudo] password for bruno: You are about to add the following PPA to your system: A simple text-based terminal screensaver.
