EUNBORNBRANCH error when adding private package

We’ve been using the package manager heavily ever since 1.0, with a dedicated private git server that contains bare git repos. Everything has always worked fine, but suddenly I find myself unable to add one of our packages:

pkg> add git://git/MyProject
  Updating git-repo `git://git/MyProject`
ERROR: GitError(Code:EUNBORNBRANCH, Class:Reference, reference 'refs/heads/master' not found)

That package has been added/updated lots of times without issue. Other packages have no such problem. Adding the package in a fresh environment causes the same issue. I can git clone the repo just fine. And the refs/heads/master file definitely exists on the git server. Does anyone have any idea? pkg> gc didn’t help either.

Also: it works on a Windows machine, but not on Linux. Julia 1.2.0

I’m assuming it works when you git clone git://git/MyProject from the command line?

Probably something similar to [SOLVED] Unable to use local package, i.e. the package got added when it didn’t have any commits at all and got borken. Try rm -rf .julia/clones.

Ideally Pkg should detect this and not cache a borken state of the repo.

Yes, it does.

That’s a 1.5 year old package, that predates Julia 1.0, so I don’t think that would be the case. rm -rf .julia/clones fixed the issue in any case, thank you!
