Well, the bug #27100 [1] is solved now, I guess. First, the command $ guix import pypi flex works now. And the command: $ guix import pypi kikoo following redirection to `https://pypi.org/pypi/kikoo/json/'... guix import: error: failed to download meta-data for package 'kikoo' fails gracefully. What remains is “guix import pypi kikoo -r” but it is tracked by #44115 about the recursive option of all the importers. Otherwise, do you have example to reproduce the bug you initiated. 1: 2: Thanks, simon
