Nginx和乘客依赖问题(数字海洋部署)

Question

我试着按照这个指南

https://www.digitalocean.com/community/tutorials/how-to-deploy-a-rails-app-with-passenger-and-nginx-on-ubuntu-14-04

当我想在运行此命令后继续学习本教程时:

sudo apt-get install nginx-extras passenger

我收到此错误:

Reading package lists... Done
Building dependency tree

Reading state information... Done
passenger is already the newest version.
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:
nginx-extras : Depends: perlapi-5.18.2 but it is not installable
Depends: libperl5.18 (>= 5.18.2) but it is not installable
Recommends: passenger (< 4.0.60) but 1:4.0.59-1~trusty1 is to be installed
E: Unable to correct problems, you have held broken packages.

我想我不能安装nginx-extras,有人可以帮我吗？

我在Ubuntu 14.10上遇到了同样的问题

sudo nano /etc/apt/sources.list.d/passenger.list

评论出来
deb https://oss-binaries.phusionpassenger.com/apt/passenger trusty main

ctrl + x
Y
输入

sudo apt-get update

sudo apt-get install nginx nginx-extras

那如果好的话

sudo nano /etc/apt/sources.list.d/passenger.list

插入
deb https://oss-binaries.phusionpassenger.com/apt/passenger wheezy main

ctrl + x
Y
输入

sudo apt-get update

sudo apt-get install passenger

瞧!

如果您使用的是Ubuntu 16.04,请执行以下操作

# Install our PGP key and add HTTPS support for APT
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 561F9B9CAC40B2F7
sudo apt-get install -y apt-transport-https ca-certificates

# Add our APT repository
sudo sh -c 'echo deb https://oss-binaries.phusionpassenger.com/apt/passenger xenial main > /etc/apt/sources.list.d/passenger.list'
sudo apt-get update

# Install Passenger + Nginx
sudo apt-get install -y nginx-extras passenger
