Hi All,

tried this command on my machine getting error

kubernetes$sudo -i kubectl config set-context --current --namespace rev3
error: no current context is set

And also no notepad was found

can anyone please help
as I’m reattempting the exam.

You should be setting contexts on candidate-node, which is the prompt you are at when you first open the terminal, not any other node you may have SSH’ed onto.

You do not require sudo - you should already have root privilege, and sudo -i will change your linux user to root from what it is when you open the terminal, and root most likely does not have a KUBECONFIG file

The notepad is the mousepad application.
