I just started getting hit by what appears to be the same issue on a
Debian system running guix whenever i guix pull...

originally stared for
me with guix successfully pulled to
bb2701b9111a3d82a82ceaaf2b22b51ecd8ac21f, and then trying to guix pull
to anything newer would trigger the issue...

I managed to workaround it by using an older guix pull at commit
e61660c78f1190c578dd6f202bc5529cbdcff84e, and then guix pull to
8663be6da7f13a8eeea71dc1f493f7adc5b7672a was successful ... but now with
8663be6da7f13a8eeea71dc1f493f7adc5b7672a it appears to be happening
again. Wow, that's confusing...
