The bug comes from the fact that it’s gone beyond 100%. We could solve
it by programming more defensively, but it’d be great to see where the
problem comes from.
Can you reproduce it with:
./pre-inst-env guix challenge
/gnu/store/5ds5bli4p6gja2yzmzzc0sik1kzrasp9-guix-extra
?
If so, could you apply the patch below and send the output of this
command? We can discuss it on IRC if anything’s unclear.
Thanks,
Ludo’.
