When I run
podman run
I'm getting a particularly weird error,
❯ podman run -ti --restart=unless-stopped -p 80:80 -p 443:443 rancher/rancher:latest
✔ docker.io/rancher/rancher:latest
Trying to pull docker.io/rancher/rancher:latest...

Error: Error committing the finished image: error adding layer with blob "sha256:b4b03dbaa949daab471f94bcfd68cbe21c1147e8ec2acfe3f46f1520db48baeb": Error processing tar file(exit status 1): potentially insufficient UIDs or GIDs available in user namespace (requested 630384594:600260513 for /usr/bin/etcdctl): Check /etc/subuid and /etc/subgid: lchown /usr/bin/etcdctl: invalid argument
What does _"potentially insufficient UIDs or GIDs available in user namespace"_ mean and how can I remedy this problem?
