Installation and compatibility with IPv6 only VPS

Hi all,
I’m trying to install Discourse on a VPS (ubuntu server 22.04 LTS) with only IPv6 but I get this error

./discourse-doctor may help diagnose the problem.

Following these guides I fixed the problems with IPv4 dns but I still can’t complete ./launcher rebuild app

Is Discourse not compatible?
If yes, then I won’t try again.

IPv6 is used extensively on their own hosting, so Discourse itself is compatible with IPv6.

Can you show more of the logs? The actual error is above the section you included. A wild guess is that something in your config is causing a problem pulling stuff from github. I don’t see any AAAA records for github, so that may be the issue. And there’s this:

I’ll add the full log soon…

After adding the dns shown here, I can use github without problems.

Hmm. But if you did that before the problems that you’re having now, it may not be enough to get docker to have access to github. Can you use github from inside of a docker container?

I changed DNS before starting the installation, docker was installed successfully with the script but I didn’t check if I can use github inside a docker container…

How can I check?
Thank you :slight_smile:

I don’t know well enough to tell you.

You’d need to crank up some container, enter it, and then try to git clone or maybe even just curl

I suspect for your IPv6-only setup it’s going to be difficult and unsupported. I with google git+clone+inside+docker+ipv6 I found this: tasks have no access to ipv6 services · Discussion #5919 · concourse/concourse · GitHub

After reading several sites and guides I decided to give up.
Too complicated and unstable, anyway thanks for your help!
