在 Virtualbox 上全新安装的 Ubuntu Server 18.04 上运行，Windows 10 作为主机操作系统。运行 Phusion Passenger 网站上的说明 here
这是我遇到的错误:
steve@heartypet-staging:~$ sudo apt-get install -y libnginx-mod-http-passenger

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
libnginx-mod-http-passenger : Depends: passenger (= 1:5.3.4-1~bionic1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
奇怪的是，完全相同的指令在桌面版本上运行良好。
最佳答案
从这里获取默认源列表

用上面链接中的文件替换/etc/apt/source.list。
然后 sudo apt update 和 sudo apt upgrade
继续……
