Velero Uninstall: Velero namespace stuck in "Terminating" state

[gh-noobie]

Hello everyone,

After uninstalling Velero, all resources were deleted, but the Velero namespace is stuck in a "Terminating" state. Has anyone encountered this before? If so, could you please share any solutions or workarounds that worked for you? I tried manually deleting the namespace with some commands, but it didn't work.
Velero version: v1.14.1
I tried these commands, but they didn't work:
velero uninstall
kubectl delete namespace velero --grace-period=0 --force
kubectl get ns velero -o json | jq '.spec.finalizers = []' | kubectl replace --raw "api/v1/namespaces/velero/finalize" -f -

Thank you in advance for your help!

kubectl get ns velero -oyaml

then we'll be able to see what's blocking.

@kaovilai, thank you for your response. I executed kubectl get ns velero -oyaml, and here is the result:

I also tried to install Velero by following the procedure outlined in this documentation:

This is not a velero specific issue. I recommend finding ways to get metric server back up.

@kaovilai, thank you for your response. I really appreciate your help! The issue has been resolved. It turns out the problem was that there were no worker nodes, which caused it to get stuck in the "Terminating" state.
