R unsupported on Xenial builds?

Hi,

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.

Full log here: https://travis-ci.org/pitrou/arrow/jobs/480547524

Indeed, https://launchpad.net/~kirillshkrogalev/+archive/ubuntu/ffmpeg-next does not show a Xenial package. I don’t know if there is a workaround. I suggest using Trusty instead at least for the time being.
