I don’t think this is a problem specific to time-machine. I ran into what
I belive to be the same issue a couple of days ago on Ubuntu, when I was
using its Guix 1.2.0 package to pull to the current version in master:

My workaround was to first pull to the commit corresponding to v1.3.0 and
then using that version to pull to current master, which worked.
