The CI on GitHub Actions passes because it runs the quick tests only, not the full set of tests. https://github.com/facebook/hhvm/blob/e25051f8e9e824966ac7898715411e58a0f21659/flake.nix#L35

Now we build universal deb packages of HHVM, which should be able to run on Ubuntu 22.04. See https://hhvm.com/blog/2022/08/30/experimenting-with-universal-deb-packages.html
