The Sysbox installer requires a docker service restart to configure network parameters, but it cannot proceed due to existing Docker containers. Please remove them as indicated below and re-launch the installation process. Refer to Sysbox installation documentation for details.
 	"docker rm $(docker ps -a -q) -f"

Most probably I have done something wrong. Needless to say Ubuntu 24 is not in supported OS. Yet as title says; just reporting.
