SSH error guix pull

[Mauritz Stenek]

I'm trying out Guix and created a personal (private) channel with 
some custom packages. I access my git repo with ssh.

Using Guix on a foreign distro, pulling from my git repo works 
fine after applying this strategy: 
https://issues.guix.gnu.org/31285.

However, on a full Guix system I keep getting this error:

```
guix pull: error: Git error: error authenticating: no auth sock 
variable
```

and, for the life of me, I just can't get it to work.

(disclaimer: I'm a total scheme/guile neophyte -- and am learning 
as I go)

Please help.
