Similar to nginx-http3, except that it only provides a single binary nginx instead of Debian package.
According to Debian Wiki, Debian bullseye will reach its end-of-life date in July 2024. Therefore, the project will switch to Debian bookworm as the packaging environment in June 2024.
First, install NGINX from nginx-http3, Debian's official package or NGINX's official package. Then run following commands.
sudo systemctl stop nginx
sudo wget https://github.com/ononoki1/nginx-quictls/releases/latest/download/nginx -O /usr/sbin/nginx
sudo chmod +x /usr/sbin/nginx
sudo systemctl start nginx
