[ubuntu] MongoDB not working after upgrading to 16.04 from 14.04

Two days back I got a notification to upgrade to 16.04.2 which I did. But now MongoDB stopped working. So I reinstalled it, even than it didn't worked the problem was with some permissions. After which I uninstalled it completely even removing folders and ppas and everything that was related (followed an answer). Still got the same error. Now I have tried the third time. I have also tried changing the permissions of

Code:

/var/log/mongodb

Code:

/var/lib/mongodb

to 755 and changing the port in

Code:

/etc/mongod.conf

. I don't want to reinstall ubuntu and therefore need help.

The error I get when trying to run mongo shell.

Code:

$ mongo
MongoDB shell version: 3.2.8

Let's block ads! (Why?)
