Unable to install Phusion Passenger on Ubuntu Server 18.04

Question

Running on a fresh install of Ubuntu Server 18.04 on Virtualbox, Windows 10 as the host OS. Ran the instructions on the Phusion Passenger site here

This is the error I'm getting:

steve@heartypet-staging:~$ sudo apt-get install -y libnginx-mod-http-passenger
Reading package lists... Done

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.

Oddly enough, the exact same instructions work fine on the desktop version.

Answer 1

Get default source list from here

https://askubuntu.com/a/1036749

Replace /etc/apt/source.list with the file in the link above. Then sudo apt update and sudo apt upgrade

And go ahead...

Answer 2

如果您对以前的解决方案有问题，一个选项是运行此命令： sudo nano /etc/apt/sources.list.d/passenger.list并注释此文件中的所有行，然后运行命令sudo apt-get install passenger
