I am installing the MEAN Stack (MongoDB, Express, AngularJS, NodeJS) in ubuntu 16.04 when installing mongo I get the following error .. someone has solved this before?

Try as follows:
1. sudo rm /var/lib/mongodb/mongod.lock
2. sudo mongod --repair
3. sudo service mongod start
4. sudo service mongod status
Goes as follows, with rm the file mond.lock is deleted; then the second step is to repair the demon / mongo service.
Attempt to restart the service / daemon called mongod
At the end if the start is successful with the last and fourth step, the status of the service is verified
The .lock file is the one that stores the configuration of the versions of some dependencies that requires mongodb to be able to function
Remember to execute the command with sudo
so that you elevate the privileges and access as root
