As I know it seems like need to run `guix pull` to update your scheme files.
I usually run updates for root and non-root users with this line:
`guix pull && guix package -u`

Also after update by root you may need to run `guix system reconfigure config.scm` with you config.scm file (that you need to have). This will update your guix-daemon.

Hope it helps!
