The CI build installed "ocaml-dune amd64 3.16.0-2+b1" according to the log at https://ci.debian.net/packages/o/ocaml-luv/testing/amd64/55951141/

However, from `getbuildlog ocaml-luv 0.5.14-1 amd64`, I can see that ocaml-luv was built with "ocaml-dune amd64 3.17.1-1".

I wonder why the CI didn't use the latest dune package?

My local sbuild used the latest dune package, but still failed because of https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1073595

Best,
Andy
