Hi, I was trying to install the package “MultivariateMoments”.

```julia
import Pkg; Pkg.add("MultivariateMoments")

```

It failed with the following error:

```julia
Unable to automatically install 'XML2' from '/Users/My_Name/.julia/packages/XML2_jll/QkZTc/Artifacts.toml'

```

What should I do to fix this? Thanks in advance!

I then installed the “DebugArtifacts” package and tried the following:

```julia
using DebugArtifacts
debug_artifact("XML2")

```

However, I’m getting the following error:

```julia

```

Are you behind a firewall or something like that? it looks like you can’t access GitHub

I don’t think so. I can access my repositories without any problem. Although, it is very weird that I just ignored the error I got from `debug_artifact("XML2")` and tried again `using MultivariateMoments`. It just worked.

Maybe a temporary error? Do you still get the same error when trying to run `debug_artifact`?

I still get the same error while running d`ebug_artifact("XML2")`…

Yes, I can view this link. It looks like

Ok, looking better to the error message, `curl` here returned 51, which should be an error relative to certificates.

Anyway, glad that you manage to install the package 🙂
