Intermittent failure caused by failing to fetch: calico manifest, k3s checksum

The exit code 22 is probably from curl:

22="HTTP page not retrieved. The requested url was not found or returned another error with the HTTP error code being 400 or above. This return code only appears if -f, --fail is used."

Curl has a --retry flag, but that won't help if it's a GitHub outage lasting several minutes.

Another kind of intermittent failure that can happen

It would be great to provide re-attempts of some kinds for both of these kinds of failures! I marked this as "help wanted"
