I’ve upgraded julia to `1.6.3` (own build), with `libgit2 1.2.0`, on `linux`.

Seems like cloning fails:

```julia
(@v1.6) pkg> add Plots#master
     Cloning git-repo `https://github.com/JuliaPlots/Plots.jl.git`
ERROR: ReadOnlyMemoryError()

```

Of course I’m connected and I can clone using a `git clone` in a terminal. Worked without issue with the same toolchain in julia `1.6.2`.  
Can anyone reproduce ?

Are there any tips for debugging `LibGit2` (env variables, …) ?

I have the same problem.

I’ve reverted temporarily to using libgit2 `1.1.0` ([https://github.com/JuliaLang/julia/blob/ae8452a9e0b973991c30f27beb2201db1b0ea0d3/deps/libgit2.version](https://github.com/JuliaLang/julia/blob/ae8452a9e0b973991c30f27beb2201db1b0ea0d3/deps/libgit2.version)).
