According to the way back machine this seems to be a recent change - the last known good link is from 2020-04-02: https://web.archive.org/web/20200402034805/https://guix.gnu.org/cookbook/en/guix-cookbook.html Is there also a reason that Russian and Chinese don't have pdfs for the cookbook or the manual? At the moment I do not have a guix development environment to experiment, so I am submitting this bug report.
