Fixing git permissions after sudo guix pull

[John]

Hi,

I ran "sudo guix pull" without thinking it through. Now when I run the command 
without sudo it gives me the error below. I assume I need to fix the ownership 
of a git repo does anybody know where that might be?

guix pull: error Git error: incorrect data check

Also no amount of --debug or --verbose give much more info is there a better 
way to see what guix is doing?

Thanks

John
