Subject: bug#46861: `guix deploy` permission denied error

When I run Guix deploy, I get this error:
```
guix deploy: error: open-file: Permission denied:
"/home/itsme/.cache/guix/checkouts/last-expiry-cleanup"
```

I've tried deleting ~/.cache/guix, and creating a chmod 777'd
~/.cache/guix directory, but I still get that error.
