Running nix on an IPv6-only host fails to instantiate nuggets and jekyll-tagging. (feddit.org)

It's these two gems, specifically. I can build them on my local machine, and nix copy them to the server, but building them directly on the server always fails with curl: (6) Could not resolve host: rubygems.org.

(If you want to replicate it: nix build https://codeberg.org/libewa/pages/archive/main.tar.gz.)

Could it be that rubygems does not support ipv6?

Some sites, even big sites don't support it: https://areweipv6yet.com/

According to the above, Github doesn't properly support it yet.

What do I do now? For GitHub, there‘s gh-v6.com, is there anything similar for RubyGems?

Idk..

Maybe you can use a VPN that acts a public ipv4 address so you can get to ipv4 only stuff reliably?

or you can use one of the public free 6to4 gateways?
