Uninstall

sudo apt remove deaconguard          # Debian and Ubuntu
sudo dnf remove deaconguard          # RHEL, Fedora, Amazon Linux
sudo rm /usr/local/bin/deaconguard   # archive install

Removing the package stops the services and keeps your data. To delete it as well:

Machine	Remove
Server	/var/lib/deaconguard/
Agent	/etc/deaconguard/
Local mode	~/.local/share/deaconguard/, or the directory in DEACONGUARD_HOME

Before uninstalling an agent, remove its host in the server's dashboard. That revokes the agent's credential on the server.
