MEAN One click installation problem with Mongodb

I have just deployed my first droplet using MEAN one click installation. Droplet started off fine and connected with SSH. Now when I try to start the example app as given in the tutorial, it fails to start because it is unable to connect to mongodb. Here is the error log:

+ Important warning: config.domain is empty. It should be set to the fully qualified domain of the app.
Could not connect to MongoDB!

Isn’t MongoDB supposed to be installed out of the box? What am I missing here?


I used the apt list --installed command and didn’t find MongoDB installed. I am installing it now but I believe it should be installed out of the box.

Also did a sudo apt-get update and got the following report:

Seems this is not fixed yet

Hi @KodeBlox

I just tried spinning up a MEAN 16.04 droplet and I’m getting the same error. Actually it seems like MongoDB is not installed, which means the initialization script also fails (/var/lib/cloud/scripts/per-once/002-mongodb)

Can you create a ticket under Support in the control panel? You can link to this thread.
