I have tried so many times uninstalling ArgoCD and reinstalling. I have no idea what I am doing wrong honestly.

I start by installing ArgoCD. I am not interested in anything fancy, so I'm trying the core installation.

kubectl create namespace argocd
kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/core-install.yaml

No errors. The guide says I can use argocd login --core to skip steps 3-5, so I do that:

cis@sd2:~$ argocd login --core
Context 'kubernetes' updated

Looks good as far as I know. Now I try to create their example application:

argocd app create guestbook --repo https://github.com/argoproj/argocd-example-apps.git --path guestbook --dest-server https://kubernetes.default.svc --dest-namespace default

... Nothing. Nothing at all happens. I'm never prompted for another command as long as I don't interrupt the process by pressing control+c. Am I vastly misunderstanding the getting started guide? I am happy to provide any necessary information about my cluster, I just have no idea what information would even be relevant.

This is the guide I am trying to follow: https://argo-cd.readthedocs.io/en/stable/getting_started/
