gns3util remote uninstall gns3

Uninstall GNS3 server from remote machine

​
Synopsis

Uninstall GNS3 server from a remote machine. This command will:
  • Stop and remove GNS3 server service
  • Remove GNS3 configuration files
  • Remove GNS3 home directory (unless —preserve-data is used)
  • Remove GNS3 packages
  • Clean up systemd services
Note: The GNS3 user account is preserved to avoid file ownership issues. The command will attempt to load installation state from a previous installation to determine the correct configuration values. If no state is found, command line flags or defaults will be used. Use —preserve-data to keep the GNS3 home directory with projects and user data. Note: This will NOT remove virtualization packages (QEMU, Docker, VirtualBox, etc.) as they may be used by other applications.
