无法在Ubuntu 14.04上安装Mongodb。 （错误＆＃34;状态：未知作业：mongod＆＃34;）

Question

我正在尝试为Ubuntu 14.04安装Mongodb。我从这里开始关注Mongodb安装的官方文档 - https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/

我运行了以下命令： -

1. sudo apt-key adv --keyserver hkp：//keyserver.ubuntu.com:80 --recv 2930ADAE8CAF5059EE73BB4B58712A2291FA4AD5
2. echo＆＃34; deb [arch = amd64] https://repo.mongodb.org/apt/ubuntu trusty / mongodb-org / 3.6 multiverse＆＃34; | sudo tee /etc/apt/sources.list.d/mongodb-org-3.6.list
3. sudo apt-get update
4. sudo apt-get install -y mongodb-org

当我执行命令＃4时，我接近输出的结尾：

Setting up mongodb-org-server (3.6.3) ...
runlevel:/var/run/utmp: No such file or directory
invoke-rc.d: policy-rc.d denied execution of start.
initctl: Unknown job: mongod
Setting up mongodb-org-mongos (3.6.3) ...
Setting up mongodb-org-tools (3.6.3) ...
Processing triggers for ureadahead (0.100.0-16) ...
Setting up mongodb-org (3.6.3) ...

在此之后，当我运行sudo service mongod start时，我得到了：

start: Unknown job: mongod

运行mongo会导致： -

MongoDB shell version v3.6.3

mongo --version会导致： -

build environment:

    target_arch: x86_64

/var/log/mongodb和/var/lib/mongodb都是空文件夹。

我已使用上面链接的相同文档页面上的说明卸载了这个，并重新安装了它。没有变化。

无法相信官方指示失败，我无法在任何地方找到解决方案。
