Build failing with "Could not resolve host: www.leonerd.org.uk"

[clason]

The server that is hosting two dependencies of neovim (libtermkey and libvterm) is currently down, so unless you have these cached (especially, if you removed them via make distclean), the build will fail. The problem is known; in the meantime, you can replace the links to the tarballs with ones to cached files:

That's from 2016, and the gitter comment you're referring to is from the same time. I see no evidence that leonerd is even aware of the issue currently.
