Can't upgrade to any docker-ce version post v20

I am surprised your docker demon even starts with this daemon.json file, as it is not a valid json.

Assumed your configuration items are correct, the daemon.json should look like this:

{
    "data-root": "/srv/Docker",
    "storage-driver": "overlay2",
    "metrics-addr": "127.0.0.1:9323",
    "experimental": true
}

Once the daemon.json is correct, try to upgrade again.

Also, please format your existing and future posts according these instructions:
