| Plugin Name: cURL no IPv6 | |
| Plugin URI: https: | |
| Description: On systems where cURL is compiled with IPv6, Requests to Wordpress Update API will timeout since cURL tries it about 15s. Since the timeout defined by WordPress is 3s/5s/10s this will breake the Updater. This Plugin simply forces cURL to use IPv4 only. | |

Thank you for creating this and sorry for the dumb question, but how do you install this in WP?
(I'm running WP on arch linux. I'm very familiar with linux and software development, but not PHP or the WP ecosystem)

Following line is redundant:
if( function_exists( 'gw_curl_setopt_ipresolve' ) ){
