The rpm or dpkg command fails to be executed. Log in to the node and check whether the following commands are available:
rpm:
rpm -qa
dpkg:
dpkg -l
Scenario 2: The systemctl status command fails to be executed.
If the systemctl status command on a node is unavailable, many check items will be affected. Log in to the node and check the availability of the following commands:
systemctl status kubelet
