This might be a dumb question, but is your MongoDB server running?

That howto did work fine for me a while ago. Did you encounter any errors during the installation of MongoDB? Looks like it is not installed (correctly).

no errors during the installation of MongoDB

[fnordsh]

Just to be sure, check that MongoDB is really there:
dpkg-query -L mongodb-org-server
Then, check if this applies to you:

@gertmenke thanks so much is working now :D

i used this link and is working now

https://www.digitalocean.com/community/tutorials/how-to-install-mongodb-on-ubuntu-14-04

but why is not working here
https://rocket.chat/docs/installation/manual-installation/ubuntu/

[fnordsh]

Probably some confusion caused by Ubuntu's switch from upstart to systemd.
Glad you got it working.
