Installing greenbone on fedora38

I am trying to install greenbone on fedora38. I am getting the following error

[root@fedora admin]# openvas-setup

Update NVT, CERT, and SCAP data

The native Linux package and associated setup and feed-sync commands are not provided directly from Greenbone. They are provided by the Linux package maintainers themselves. As far as I know, Fedora38 packages are not actively being maintained. You should contact the maintainers at Fedora or open a bug track or ask in the Fedora community forum.

In this case this looks like a networking / connectivity issue (e.g. Firewall blocking rsync, …). Please check existing threads about the same message for more information.
