Ways to Install or Uninstall watchdog on Ubuntu 22.04

Updated: September 9, 2022

The watchdog program writes to /dev/watchdog every ten seconds. If the device is opened but not written to within a minute, the machine will reboot. This feature is available when the kernel is built with “software watchdog” support (standard in Debian kernels) or if the machine is equipped with a hardware watchdog (in which case this package can also be used to “pet” it, resetting its timer). In this guide, I will show you how to install watchdog on Ubuntu 22.04.

Prerequisites

  • OS: Ubuntu 22.04 is needed for watchdog to work
  • Privileges: Check that you can run sudo commands.
