Recommendations

None of these items are required in order to continue with the upgrade right now. However, they will be required in a future version of IPS Community Suite. You should make a note of them and contact your hosting provider or system administrator after the upgrade to address them. You can re-run these checks later from the Supportsection of the Administrator Control Panel.

You do not have the cURL PHP extension loaded. While this is not required, it is recommended.

How to load this extension? Thank you!

Contact your web host to ask them.

Nothing to do

Did you recompile your PHP with php_curl.so extension? of course if you have control of your php.ini, add "extension=php_curl.so" to the extension section, that will probably solve your issue, because it solved mine.
