# To prevent your Linux system from suspending or going into hibernation, you need to disable the following systemd targets:
# sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target

# To re-enable the suspend and hibernation modes, run the command:
# sudo systemctl unmask sleep.target suspend.target hibernate.target hybrid-sleep.target
