 * Hi all,
 * I have the distict impression that WordPress has serious problems on systems 
   that are fully IPv6 enabled.
 * Tonight I installed WordPress fresh and clean on my Raspberry Pi with Debian 
   Stretch and Apache 2.4. Ports 80 and 443 are open.
 * When I e.g. go to wp-admin/plugin-install.php I get the “An unexpected error 
   occurred. Something may be wrong with WordPress.org or this server’s configuration.…”
   Debug says the error occurs in wp-admin/includes/plugin-install.php on line 168.
   The access.log says it happens when my site is accessed via IPv6.
 * Searching the Internet, including these forums, for an explanation and perhaps
   a solution, most of the times it is said that (php-)curl can’t connect to wordpress.
   org. On the command line, e.g. curl api.wordpress.org is successfull. But the
   IPv6 version, curl -6 api.wordpress.org, is not. WordPress.org appears not to
   have an IPv6 address.
 * The obvious solution would be to make WordPress addressable over IPv6, but I 
   understand that has quite some technical and financial implications. The other
   option seems to me to alter WordPress in a way that it will only ‘curl’ via IPv4.
 * The SaFly Curl Patch does not solve this issue. That also addresses only issues
   with wordpress.org, though the problem seems to include e.g. Jetpack’s wordpress.
   com.
 * What other explanation can be tested? And if there is no other explanation possible,
   how to make the problem mended in WordPress?
 * Please, prove me wrong?
 * Paul

 * WordPress does not use IPV6, so you’ll need to set your system to use the an 
   IPV4 lookup.

 * Oh, I thought your name was familiar. You’re already in that thread, so you read
   Otto’s reply. As they say on Law and Order, “Asked and answered!”.
