I am trying to install specific version of FFMPEG (4.1.4), but, when I try to execute:
sudo add-apt-repository ppa:mc3man/trusty-media
I get following error message:

Same thing happens once I try and execute sudo apt-get update. I honestly dont have much experience with Linux, I saw that people tried edditing /etc/apt/sources.list but I am really not sure which line should I comment out or even if that is the right approach. Any ideas?
