@henilp105 does this affect any other fpm activity? As in, do we call git_archive in any a context other than the registry integration at the moment?

[henilp105]

@gnikit No, The git_archive functionality is only used to publish a tarball to the registry. This bug doesn't affect any other fpm functionality. the tarball uploaded on the registry must contain a fpm_model.json file, which was not getting attached in v0.10.1 to handle this in an interim manner a patch fortran-lang/registry#75 has been made on the registry side to generate and attach the fpm_model.json file to the tarball on the server side, This is a permanent fix for the bug.

My edit reflects @gnikit (and my) concern to not lose the option to call git_archive from elsewhere. LGTM with this edit, let's see what Giannis thinks.
