The source is at https://github.com/varnish/varnish-modules but I couldn't build it.
Ideally I'd want something installable through a ppa. The closest I could get was https://launchpad.net/~lasse-karstensen/+archive/ubuntu/varnish-modules but this is old and doesn't have support for 20 (only for 18).
I'd also be OK to install it from a .deb or .rpm file if one exists and is possible.
