Cron doesn't work

Support
1

I want to schedule a shutdown at 22:05 on thursday and 19:05 the rest of the week

i tried, without success, this:

~ >>> crontab -e
SHELL=/bin/zsh
05 19 * * 0,1,2,3,5,6 /usr/bin/shutdown -h now
05 22 * * 4 /usr/bin/shutdown -h now


~ >>> sudo crontab -e
SHELL=/bin/zsh
05 19 * * 0,1,2,3,5,6 /usr/bin/shutdown -h now
05 22 * * 4 /usr/bin/shutdown -h now

Probably the problem is that cron isn’t active, but no idea how to do it.

~ >>> systemctl status cronie                                                                                                                                                                                    [3]

Enable cronie.service with

systemctl enable --now cronie.service

Also the shutdown command might require higher privileges. If it doesn’t work in your user crontab, add it to the system crontab (executed as root user), or at the personal crontab of the root user.
