guix pull ssh authentication error

[Mauritz Stenek]

I'm trying out Guix in a virtual machine and am trying to pull 
from a personal channel through ssh, but I keep getting this 
error:

```
guix pull: error: Git error: Failed to retrieve list of SSH 
authentication methods: Failed getting response
```

Any ideas on how the resolve this?

Poking around the internet, it seems that it might be a problem 
with libgit2.

Thanks.
