Does anyone have idea how to fix it?  
Thanks a lot!

What operating system?

Also, are you using the official binaries downloaded from [JuliaLang.org](http://JuliaLang.org)?

Seems related to [LibGit2.set\_ssl\_cert\_locations segfaults on a cluster · Issue #17789 · JuliaLang/julia · GitHub](https://github.com/JuliaLang/julia/issues/17789)

You may want to comment on that issue.

Haha an old issue.

The workaround is

```julia
$ julia
               _

   _ _ _| |_ __ _ | Type "?" for help, "]?" for Pkg help.

julia> LibGit2.set_ssl_cert_locations("/etc/ssl/certs/ca-certificates.crt")
0

julia> 

```

The workaround has to raise an error first, so there is no good way to put them in the startup script.
