Installation error on amazon linux 2 amazon-eks-node instance

[amitay-strattic]

Installing via user-data on ami: amazon-eks-node.

I am installing the helper like this:

wget https://s3.amazonaws.com/remote-collector/agent/v24/install_cht_perfmon.sh -O install_cht_perfmon.sh;
sh install_cht_perfmon.sh 24 $KEY aws;

I get the following error in the logs:

Thank you for installing agent!
