Ubuntu Server firmware update—Manual method
Follow these steps to update the Ubuntu Server firmware manually.
Search for the Edge Gateway firmware.cab file at fwupd.org/lvfs/devicelist and copy it to the target device.
1. Display all devices detected by the fwupd command.
# sudo fwupdmgr get-devices
2. Install the downloaded firmware.cab file.
# sudo fwupdmgr [Installation path of firmware.cab] -v
3. Reboot the system to install the updates.
# sudo reboot
Configure Watchdog Timer (WDT)
We recommend to enable the WDT by default to activate the fail-safe circuitry.
For more information about WDT, see:

Configuring Watchdog Timer (WDT)
We recommend to enable the WDT by default to activate the fail-safe circuitry.
1. Show the available WDT settings.
# cat /etc/watchdog.conf
NOTE:
If watchdog-timeout= is set to a non-zero value, the watchdog hardware (/dev/watchdog or the path specified
with WatchdogDevice= or the kernel option systemd.watchdog-device=) will be programmed to automatically reboot
the system if it is not contacted within the specified timeout interval.
2. Show the WDT environmental settings.
# cat /etc/default/watchdog
