Note: The agents must be on version 11.1 for the Schedule to run on the devices.

To run Linux Package Upgrades, go to Security and look for the new section "Linux Package Upgrades".

1. Go to Schedules > Choose Action > New
2. Add a unique name to the Schedule
3. For Action Select Either "Detect All" or "Detect and Upgrade All"
4. Filter which devices will run on this schedule
5. Select either "No Reboot" or "Force Reboot" option. In some cases, the selected devices are automatically rebooted after package upgrades are installed. This is outside the control of the agent, and the reboot is triggered by the Package itself.
6. Select a time in which the Schedule will run
7. Click Save

After the schedule is created, a preview will be seen of the devices that will run it when executed.
