You are trying to time-travel to something before the introduction of time-travel. Hence the unexpected behaviour, I guess. Thanks for reporting that something is missing. The inferior should stop and error out. It does not because ’cached-channel-instance’ is currently called with the argument ’#:validate-channels’ set to the default (const #t). Currently, the verification is only done in guix/scripts/time-machine.scm. Well, this issue seems being part of bug#65788 [1]. 1: bug#65788: poor information when updating using “guix time-machine” Simon Tournier <zimon.touto...@gmail.com> Wed, 06 Sep 2023 18:57:38 +0200 id:87pm2vme7x....@gmail.com https://issues.guix.gnu.org/65788 https://issues.guix.gnu.org/msgid/87pm2vme7x....@gmail.com https://yhetil.org/guix/87pm2vme7x....@gmail.com Cheers, simon
