I’m quite new to Julia, and after a fresh installation I’m running into the following error:

```julia
julia> Pkg.update()

I had the same problem in Archlinux. The answer I found is:

1. Install Downgrade
2. Downgrade libgit2 to version 1:0.24.6-1

This question has been solved in Archlinux with a new package of Julia 0.5.1 compatible with libgit2 1:0.25.1-2.
