Invalid checksum for package ctypes_stubs_js.0.1

[mjambon]

The expected checksum is

#=== ERROR while fetching sources for ctypes_stubs_js.0.1 =====================#
OpamSolution.Fetch_fail("https://gitlab.com/nomadic-labs/ctypes_stubs_js/-/archive/0.1/ctypes_stubs_js-0.1.tar.gz (Bad checksum, expected sha256=74ab170e064bff88eaa592efc992d24fa1665c67047fc822276eae52c0f3384d)")

The new checksum I'm getting is

$ wget https://gitlab.com/nomadic-labs/ctypes_stubs_js/-/archive/0.1/ctypes_stubs_js-0.1.tar.gz
$ sha256sum ctypes_stubs_js-0.1.tar.gz 
7c40ffcfda29cb407cb05b7837fe0dc46e18acc8b9a023afb58aa8751ec795e1  ctypes_stubs_js-0.1.tar.gz

Not the same package, but also a checksum issue with GitLab-generated tag archive.
Over the last few days I've seen similar errors with the json-data-encoding package, e.g.:

#=== ERROR while fetching sources for json-data-encoding.0.12.1 ===============#
OpamSolution.Fetch_fail("https://gitlab.com/nomadic-labs/json-data-encoding/-/archive/0.12.1/json-data-encoding-0.12.1.tar.gz (Bad checksum, expected md5=f70939e5bcaae19f5996e05d3baf5536)")

Also for other versions of it, e.g. 0.8.

Also, some builds seem to not get the error while others do, so maybe there's something broader going on on the GitLab side with different hosts serving differently checksummed archives?

Apparently it's going to be fixed today or tomorrow according to #23589 (comment)

In the meantime if you use

opam repo set-url default https://opam.ocaml.org

instead of the git repository, the opam cache should be used by default, or if you want to keep using a git repository you can use

opam option 'archive-mirrors="https://opam.ocaml.org/cache"'

This specific issue is fixed in the opam-repository. Thanks for your report.
