Package manager breaks if your current pwd contains a file or directory called "libgit2"

[Keno]

$ mkdir libgit2; julia -e 'using Pkg; Pkg.update()'
    Updating registry at `~/.julia/registries/General.toml`
ERROR: could not load library "libgit2"
libgit2: cannot open shared object file: No such file or directory

This is caused by a combination of:

1. The LibGit2 stdlib uses plain libgit2 as the library name
2. We stat the literal name passed in jl_dlopen and don't query the extensions if the file exists

It worked for me when copying the exact command that you've written. You should check if there's some problem with you're connection or computer, or you should be more specific about your problem
