I’m running into difficulties using PkgTemplates to setup a package. I made a tiny package [here](https://github.com/LilithHafner/Example.jl)

But when I try to add it at the repl, it fails:

```julia
(@v1.8) pkg> add https://github.com/LilithHafner/Example.jl
ERROR: invalid git HEAD (reference 'refs/heads/main' not found)

```

What does this error mean?

I was able to add your package, no problem. Which means you’ve done it right! 🙂 If it’s still not working maybe you’ve messed up something locally?

Very strange. I deleted most of ~/.julia and tried again and it worked. Thanks.
