yes

What type of issue is this?

No response

A clear and concise description of the issue.

Because there's no ipv6 address for www.github.com (it's 2025 and still working on it)

> nslookup -type=AAAA github.com 1.1.1.1
Server: one.one.one
Adress: 1.1.1.1

a workaround would be to use the raw.githubusercontent.com domain whch has. Also the internals scripts use the raw.githubusercontent.com.

Which browser are you using?

Chrome

If relevant, including screenshots or a code block can be helpful in clarifying the issue.

No response

Please provide detailed steps to reproduce the issue.

@vesnikos commented on GitHub (Mar 14, 2025):

When I copy/paste a script e.g. :

Image

in the console of a box configured only to use ipv6

Image

it silently fails

Image

The root reason is that github.com cannot resolve to an ipv6 because there's no AAAA in any DNS. this is an issue of github.com as have not provided one of their domain. this can be verified at https://api.github.com/meta

As a workaround I need to manually edit the scripts domain to use https://raw.githubusercontent.com...

hm i doesnt use only ipv6, its hard to fix this.

Does work the wget call? (without bash).
Idk where i can fix this, because i cant change the wget for all. The effects are uncertain, as there is sometimes much more to it than a simple call.

i've said it privately, gonna repeat it here. having only ipv6 networking is really going to hurt you @vesnikos since not even the biggest players on the global internet space addopted it.

you can have both ipv4 and ipv6 addresses assigned on your network. when github turns on ipv6, just disable ipv4

wget is very happy to work with ipv6 even without the -6 flag

The only real universal solution I see here is replace the pointer the website for the scripts from github to githubusercontent

ie from:

bash -c "$(wget -qLO - *https://github.com*/community-scripts/ProxmoxVE/raw/main/misc/post-pve-install.sh)"

to

bash -c "$(wget -qLO - *https://raw.githubusercontent.com*/community-scripts/ProxmoxVE/main/misc/post-pve-install.sh)"`

Idk where i can fix this, because i cant change the wget for all. The effects are uncertain, as there is sometimes much more to it than a simple call. `wget` is very __happy__ to work with ipv6 even without the -6 flag The only real universal solution I see here is replace the pointer the website for the scripts from **github** to **githubusercontent** ie from: ~~~bash bash -c "$(wget -qLO - *https://github.com*/community-scripts/ProxmoxVE/raw/main/misc/post-pve-install.sh)" ~~~ to ~~~bash bash -c "$(wget -qLO - *https://raw.githubusercontent.com*/community-scripts/ProxmoxVE/main/misc/post-pve-install.sh)"` ~~~

This is a bit off-topic with the nature of the ticket; i'd love to read your opinions on either if IETF gone wrong or if cisco has dropped the ball somewhere with their ipv6 impelementation in within IOS XE or there is a lack of training from network engineers, in a blog or something if you have

@MickLesk commented on GitHub (Mar 19, 2025):

GitHub.com still doesn’t support IPv6 (no AAAA records), which makes things tricky for IPv6-only users. While raw.githubusercontent.com works with IPv6, we won’t automate the switch because it could cause unexpected issues in different environments.

Instead of checking IPv6 and changing URLs dynamically, we’re leaving this as a manual adjustment. If you're on an IPv6-only network, you’ll need to swap github.com with raw.githubusercontent.com yourself.

Hopefully, GitHub enables IPv6 at some point, but until then, this is something that has to be handled manually.

We might reconsider this in a future refactor of the website, but that would mean evaluating client-side network data (IPv6-only detection), which we prefer not to do. Also, many existing scripts are built around github.com, so changing this would be a major structural shift.

The explanation sounds good to me! Doing the change manually is easier in that context. If there's a place in the website, it would be nice if you had a pointer to this ticket, as it also describes the workaround steps.

thanks. it seems to work. Noticed a warning when tried to install iventoy

curl: (7) Failed to connect to api.community-scripts.org port 80 after 1 ms: Couldn't connect to server

I did a
nslookup -type=AAAA api.community-scripts.org
which came back nothing

But other than that it works
