ocamlwiki seems to be a LLM-filled website. I would encourage you to avoid it, see this discussion: [What's up with ocamlwiki?](https://discuss.ocaml.org/t/whats-up-with-ocamlwiki/13605)

as for this, this is pretty simple. The file mentioned above was somehow removed (how is the mystery) and `opam update` simply redownloads the repository and sync it with what you have locally so in this case it saw that the file was missing and copied it back.

Could you submit a bug report in the [opam bugtracker](https://github.com/ocaml/opam/issues/new) with the result of `opam config report` and the output of the failing command?

Given another user reported a similar issue a few days ago on [here](https://discuss.ocaml.org/t/discover-ml-no-such-file-or-directory-when-installing-dream/13988) I’m wondering if there are something in common between you two. cc @dromas
