If you want to modify the gnome-schedule for root user ensure that you run it from terminal: gksudo gnome-schedule If you feel better doing it graphically you can install from the Software Center gnome-schedule. So you can edit the crontab for the root user. If you want to be strict about the reboot time just digit sudo crontab -e Using the shutdown command this way the system will schedule a restart 1 minute from when you ran the command. All you need to do is use sudo, followed by shutdown, and finally the -r option. To understand better what you're doing remember that in /etc folder you generally find configuration files and there you can find cron.hourly, cron.daily and other cron folders.Ĭron takes care of executing applications and script at a certain time.

Because its a server, I dont have a window manager installed, so I cant do it from a GUI (which always seems to work). If you feel like doing in using terminal just: sudo chmod +x /etc/cron.daily/zz-reboot sudo reboot now never seems to work for me. You can just copy and paste the information below in any text editor and create the zz-reboot file in the directory suggested.Īfter that just remember to right click on the file and assign it execution permission. You should create a script using the directions given by Kees Cook.

And after that you can use sudo in your commands in current session without need to restart. If the return is empty, the files are in order.Įnable and start the timer by running sudo systemctl enable sched-reboot.timer and sudo systemctl start sched-reboot.timer. After add user to sudo group, su - root -c 'usermod -aG sudo username ' execute following command: newgrp sudo. (Optional) Run systemd-analyze verify /etc/systemd/system/sched-reboot.* to check for errors in the config files.

To do that, create a new file in /etc/systemd/system/rvice and add the necessary configuration into it. Filenames and unit descriptions in the example are chosen arbitrarily and can be changed.Īdd a service unit that restarts the system. This is an older question, but it comes up as search result and does not contain any info about systemd, so I will add an example on how to do scheduled reboots with systemd.
