Tweak needed to run build job successfully

[joyrexus]

It looks like the builds are failing when trying to install the AWS CLI because a pre-existing CLI is already in place:

Found preexisting AWS CLI installation: /usr/local/aws-cli/v2/current. Please rerun install script with --update flag.

You might just need to tweak this line from the workflow file to ...

sudo ./aws/install || sudo ./aws/install --update

... or ...

sudo ./aws/install || echo "Found preexisting AWS CLI installation" 

... to ensure the CLI gets installed and doesn't fail if it pre-exists.

The error says Found preexisting AWS CLI installation, so I think if you comment that step install AWS CLI altogether you can get rid of it:
