我是juju魅力的新手，我正在尝试按照youtube教程安装juju charm工具
https://www.youtube.com/watch?v=BQ_blv9JhCs
我在windows box上为ubuntu安装了vm镜像。 ubuntu版本的详细信息是 -
Linux vagrant-ubuntu-vivid-64 3.19.0-21-generic＃21-Ubuntu SMP Sun Jun 14 18:31:11 UTC 2015 x86_64 x86_64 x86_64 GNU / Linux
我能够成功地运行教程中提到的步骤直到＆＃34; juju bootstrap＆＃34;。仅限于juju bootstrap，我收到以下错误 -

我尝试过destroy-environment并再次运行bootstrap命令。从juju-mongodb安装的消息看来，但我看不到服务正在运行。我无法使用 -
运行服务sudo service mongodb start。
输出是 -

我做错了什么？如何检查mongodb是否安装正确？
谢谢，
