The Pod is probably not yet scheduled to a Node.
Maybe it just took a little longer than expected or perhaps it's asking for resources that no node can satisfy at the moment.
Check the output of kubectl get pod kubia-zgxn9 and see if the state is Running. If so, retry now. If it still fails to exec this might be a bug.
If it's not running, check the describe output for notices. (Unfortunately you cut the output short in your question so we can't see what's wrong with it).
