Ubuntu 22 installation fail

[martinkbs]

@girish I am trying to install Cloudron on a fresh Ubuntu 22.04 installation and the installation process stops and does not complete.

@martinkbs does the server have IPv6 enabled? Does curl https://ipv6.api.cloudron.io/api/v1/helper/public_ip work ?

[martinkbs]

@girish No, not work

root@vmiXXXXXXX:~# curl https://ipv6.api.cloudron.io/api/v1/helper/public_ip
curl: (7) Couldn't connect to server

But in a testing instance of Oracle, curl https://ipv6.api.cloudron.io/api/v1/helper/public_ip is not working either and is installing Cloudron without any problem

[girish]

@martinkbs Oh. So, default ubuntu 22 unbound install on non ipv6 servers fails Guess, we have to workaround this in our installer.

@martinkbs this is on contabo correct? I will give it a try to see why the installation fails.
