Pods struck in containercreating state for ever

I have just installed kubernetes as suggested in “kubernetes for beginners” course. After i have installed i tried deploying a nginx container by running the command “kubectl run nginx --image nginx”. When i viewed the status of the pod, it is in “container creating” state and is struck in this state for ever.

Error Message: -
Failed to create pod sandbox: rpc error: code = Unknown desc = [failed to set up sandbox container “0680ac4d650346b4adab047933d843fcc0cd38ecaf9955ce015ffab1c2023716” network for pod “nginx-6db489d4b7-qghkq”: networkPlugin cni failed to set up pod “nginx-6db489d4b7-qghkq_default” network: failed to find plugin “calico” in path [/opt/cni/bin], failed to clean up sandbox container “0680ac4d650346b4adab047933d843fcc0cd38ecaf9955ce015ffab1c2023716” network for pod “nginx-6db489d4b7-qghkq”: networkPlugin cni failed to teardown pod “nginx-6db489d4b7-qghkq_default” network: fork/exec /opt/cni/bin/calico: text file busy]

Hi, the errors does seem to point clearly to an issue with the CNI.

Can you check the logs for : calico-node-rd8k9 0/1 CrashLoopBackOff 78 2d1h ?

The agents seem to be running on the other nodes so perhaps an issue with a single node?
try deleting the pod and have it create on another node to test.
