Start with the reported agent-pod startup log and the container checks for /usr/bin/lxcfs and its version output. Trace why nsenter cannot execute lxcfs in the target mount namespace, then verify the agent pod starts without that error; the repository notice says this project is no longer maintained and points to another project.
