Kube-proxy doesn't start in Minikube - permission denied with /proc/sys/net/netfilter/nf_conntrack_max

After updating Manjaro Linux and restarting the system, Minikube fails to start because of kube-proxy. The logs show it was trying to modify /proc/sys/net/netfilter/nf_conntrack_max but it ran into a permission denied issue.

Can anyone tell me how to fix this?

$ kubectl get pods -n kube-system

I found someone, who faced the same problem here (but I do not know why it deleted).

Kernel: 5.10.36-2-MANJARO x86_64 bits: 64 Desktop: Xfce 4.16.0 Distro: Manjaro Linux 

Hi, I had the same problem

please do the follow steps in console

  1. minikube delete
  2. sudo sysctl /proc/sys/net/netfilter/nf_conntrack_max=393216
  3. minikube start (apply the tag need if you are using VM)

after this run the same command kubectl get pods -n kube-system
