Hello. We appreciate the contribution! Would it be possible to attach logs here from the output of the installation script reproducing the issue to help me better understand? Thank you!

The line just apply the manifest.
The try will be re-doing the same command each 2 seconds :

kURL/scripts/common/common.sh

Lines 440 to 458 in c09c7fb

	# try a command every 2 seconds until it succeeds, up to 30 tries max; useful for kubectl commands
	# where the Kubernetes API could be restarting
	function try_1m() {
	local fn="$1"
	local args=${@:2}
	n=0
	while ! $fn $args 2>/dev/null ; do
	n="$(( $n + 1 ))"
	if [ "$n" -ge "30" ]; then
	# for the final try print the error and let it exit
	echo ""
	try_output="$($fn $args 2>&1)" || true
	echo "$try_output"
	bail "spent 1m attempting to run \"$fn $args\" without success"
	fi
	sleep 2
	done
	}

So, why would need to be required to re-duo kubectl apply many times?
What would be solved with that?

+1 to the @emosbaugh comments. That would be great if you could share the problem, and all logs of the issue that you are facing so we can better check it out and see how we can help.
