These are the Linux distributions tested in OPAM CI:
Arch isn’t on there, so the depexts are probably very bitrotted in opam. Two equally good courses of action are:
- contribute support for your favourite distro (e.g. Arch) to GitHub - ocurrent/ocaml-dockerfile: OCaml interface for creating Dockerfiles so that it can get on the supported list
- switch to one of the supported distros on the list for an immediate boost in opam build quality
I’d really like to see more non-mainstream distros in our CI list, so this is a valuable area for new contributors.
