I’m trying to move our Trusty-based Travis-CI setup to the newer Xenial images.
However it fails updating from one of the apt repositories:
W: The repository 'http://ppa.launchpad.net/kirillshkrogalev/ffmpeg-next/ubuntu xenial Release' does not have a Release file. E: Failed to fetch http://ppa.launchpad.net/kirillshkrogalev/ffmpeg-next/ubuntu/dists/xenial/main/binary-amd64/Packages 404 Not Found E: Some index files failed to download. They have been ignored, or old ones used instead.
