Thanks for attempting this major upgrade! I think that using `guix environment python-minimal` will not get you the exact environment that exists while building with the daemon. Without the '--pure' or '--container' options, `guix environment` augments your existing environment rather than replacing it. Also, the 'python-minimal' offered by `guix environment python-minimal` is likely the one that lives on the master branch, deployed by `guix pull`, unless you symlinked your git checkout to '~/.config/guix/latest'. Could you try something like this, having checked out the branch where you are attempting this upgrade: `~/src/guix/pre-inst-env guix environment --pure python-minimal` I would suggest '--container' but you'd have to make some changes to your system if you are on Debian. You could also try to source the 'environment-variables' file in the failed build directory, although you will again want to unset your pre-existing environment first (I'm not sure how to do that). Sorry if I've misunderstood your dilemma.
