Why are there no nightly builds for Ubuntu Xenial 16.04? There are builds for the 16.10 and 17.04, but 16.04 is the LTS, and therefore the most used. The latest build for 16.04 is 13.01 in the xenial repositories.
Unless the dist has become easier to set up for build in the last 3 years it takes some time to do, but I would be happy, once I get set up, to build nightlies for 16.04, if it is just a manpower issue.
