cannot pull from local copy of Guix repository

[Adam]

Hello Guix, I thought about writing a package definition. For this
purpose I usually use my Guix channel but this time I decided to clone
the main repository and try to tinker. Long story short
```
Updating channel 'guix' from Git repository at
'file:///home/user/Downloads/guix'...
guix pull: error: Git error: object not found - no match for id
(9edb3f66fd807b096b48283debdcddccfea34bad)
```
I put this repo locally and guix cannot pull from it.
Any tips on how to properly pull from a local copy of Guix?
