the certificate has expired

[TravisRoad]

Environment

• OS: Arch Linux x86_64 6.1.4-arch1-1
• Kubernetes version: v1.16.14
• VirtualBox version: v7.0.4
• Vagrant version: 2.3.4

What I did?

I just follow the readme, and copy the conf/admin.kubeconfig to ~/.kube/config. When I use kubectl get nodes, it shows

Unable to connect to the server: x509: certificate has expired or is not yet valid: 
current time 2023-01-09T22:08:46+08:00 is after 2023-01-09T09:34:00Z

I'm a newbie learning the k8s. I find this on stackoverflow, but I cannot find /etc/kubernetes/pki/apiserver.crt. Maybe I should modify the change the conf/admin.kubeconfig? Thanks in advanced.
