Since #3082, we use latexmk command to build PDF.
so you need to install latexmk package.
http://packages.ubuntu.com/xenial/latexmk

Thank you

The merged PR #3082 contained an update to the builders docs (19558c9), but I had not yet updated CHANGES, now done at 538f55e. By the way, perhaps the info at 19558c9 should be moved to location more visible in Sphinx docs ?

Okay, let's add "dependency" section to CHANGES file.
