我用 debian-10 开始了我的新服务器安装。
nginx 工作正常，由安装apt install nginx-full
但随后想要安装乘客，以这种方式https://www.phusionpassenger.com/library/install/nginx/install/oss/stretch/（未列出破坏者），我无法获得它运行。
1) sudo apt-get install -y dirmngr gnupg
2) sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-3) keys 561F9B9CAC40B2F7
3) sudo apt-get install -y apt-transport-https ca-certificates
# Add our APT repository
4) sudo sh -c 'echo deb https://oss-5) binaries.phusionpassenger.com/apt/passenger stretch main > /etc/apt/sources.list.d/passenger.list'
5) sudo apt-get update
# Install Passenger + Nginx module
6) sudo apt-get install -y libnginx-mod-http-passenger
=> 在第 5 步，结果是：
root@33041:/# apt update

问题：
a) 有人带 nginx 和乘客在 debian-10 上运行吗？（我不想从源代码重新编译 nginx，像这样）
b）如果没有，还有哪些其他推荐的方法（nginx 作为 puma 的代理 ..）？
谢谢，克里斯
