Hi Timothy, Is the 'guix' being invoked with 'sudo' the one created by 'guix pull' (~/.config/guix/current/bin/guix)? I suspect it isn't.
You can verify with $ sudo guix describe and $ sudo which guix ('which' is often not the best answer to 'which binary will run?', but here it is.) If 'sudo' is invoking a different 'guix' than the one in your user's PATH, you need to configure it to do so or explicitly use $ sudo -E guix system reconfigure … IIRC. YMMV. CYA. IANAL. Kind regards, T G-R Sent on the go. Excuse or enjoy my brevity.
