Description Laurentiu Pancescu 2016-01-24 08:34:24 UTC

I only noticed yesterday evening that the automatic remote backups, triggered twice daily via a user crontab, had stopped working after the upgrade from F22 to F23 (performed last weekend).  I found log messages like the following:

Jan 23 19:42:01 localhost.localdomain crond[1111]: (meike) Unauthorized SELinux context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 file_context=unconfined_u:object_r:user_cron_spool_t:s0 (/var/spool/cron/meike)
Jan 23 19:42:01 localhost.localdomain crond[1111]: (meike) FAILED (loading cron table)

Unfortunately, restorecon only displays a warning about missing the default context for that file; I also removed the crontab with "crontab -r" and recreated it with "crontab -e", but this results in the same SELinux context - the backup doesn't run, and I see the same log message mentioning SELinux again.  Does the latest SELinux policy require userspace changes in crontab?

I get this too, and I too recently upgraded from :
