Recommended action: Install Docker natively (not snap), ensure daemon.json has runtimes.sysbox-runc.path=/usr/bin/sysbox-runc, then restart Docker. Option: Install Docker natively (not snap), ensure daemon.json has runtimes.sysbox-runc.path=/usr/bin/sysbox-runc, then restart Docker. [evidence: official_recommended_action] Applies when: docker run --runtime=sysbox-runc (Docker-in-Docker without --privileged) Steps: 1. snap list | grep docker (remove snap Docker if present). 2. Add {"runtimes":{"sysbox-runc":{"path":"/usr/bin/sysbox-runc"}}} to /etc/docker/daemon.json. 3. sudo systemctl restart docker Expected: The error no longer appears. Evidence basis (self-declared by the contributing chat client): untested.
