2. Info: Installing Ruby-3.2.2 (very looong but passed)

Hello,
It may look like a temporary network issue, but if you tried with both webadmin and CLI, that’s twice in a row. I saw some comments on [IPv6 connection being unreliable](https://stackoverflow.com/questions/51201517/ruby-cant-connect-to-rubygems-org) or [SSL version](https://github.com/rubygems/rubygems/issues/2342). Let’s investigate, what’s the output of the following commands?
```auto
curl -4 https://rubygems.org
curl -6 https://rubygems.org
openssl s_client -connect rubygems.org:443
```
(exit that last command with CTRL+C)

in
/etc/network/interfaces
commented ipv6 related records
then openssl s\_client -connect [rubygems.org:443](http://rubygems.org:443/)
worked

The problem seems to be solved. Was an ipv6 connectivity issue but I had to deactivate it on my instance.
The strange thing is that
```auto
openssl s_client -connect rubygems.org:443
```
tried to connect only via ipv6
