When I run the ee site create command I get this:
Running pre-update checks, please wait... Setting up NGINX configuration [Done] Setting up webroot [Done] Downloading WordPress [Fail] Oops Something went wrong !! Calling cleanup actions ... 'ee_mysql_grant_host'
run as root:
ee stack remove --wpcli
