I run a server which builds and offers all latest nginx (and many other packages) deb releases for Debian and Ubuntu latest distributions:
- Debian (Bookworm at the time of writing): https://git.sdxlive.com/DR/tree/Debian/pool/stable/n/nginx
- Ubuntu (Jammy at the time of writing): https://git.sdxlive.com/PPA/tree/Ubuntu/pool/stable/n/nginx

It's my way of giving back to the open source community.

Btw, I'm facing some difficulty setting up an authentication server for a Mail Proxy Server. I would be grateful if anyone could give me a hand: https://forum.nginx.org/read.php?11,294991,295002#msg-295002
