I debugged it a little with ls -l/cat /etc/localtime, and it definitely exists, but is a regular file. Confusingly, this only causes a problem on koji, not in local mock, even though manually running similar code as the test appears to trigger the same warning as on koji. Looking at the R source code for Sys.timezone(), I've found that it checks the TZ envvar before timedatectl & /etc/localtime, so setting TZ works around the problem for me (and also silences timedatectl's warnings.) Since I have a workaround now and it doesn't reproduce on local mock, I won't bother spamming koji with debug attempts. > > -- Petr -- Elliott _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
