Can't launch mongodb

Question

I don't know where I went wrong, but there is an error after error going on here, first it was

STORAGE  [initandlisten] exception in initAndListen: 20 Attempted to create a lock file on a read-only directory: /var/lib/mongodb, terminating

I fixed with addition of permissions with this command:

sudo chmod -R go+w /var/lib/mongodb

, then

couldn't open /var/lib/mongodb/local.0 Operation not permitted

fixed it with another sort of permissions(

sudo chown -R $USER /var/lib/mongodb

)

now its complaining about:

F JOURNAL  [initandlisten] dbexception during recovery: 13544 recover error couldn't open /var/lib/mongodb/journal/j._0
2017-11-20T13:19:16.443+0200 I STORAGE  [initandlisten] exception in initAndListen: 13544 recover error couldn't open /var/lib/mongodb/journal/j._0, terminating

Update: Fixed that as well with

sudo chown -R mongodb:mongodb /var/lib/mongodb

now its

exception in initAndListen: 13440 bad offset:0 accessing file: /var/lib/mongodb/local.0. See http://dochub.mongodb.org/core/data-recovery, terminating

what is happening? I mean my Ubuntu is not some super secured version, I wish there was some

mongod --repair

command for me to use, but there isn't, whenever I try to do it it complains about

exception in initAndListen: 29 Data directory /data/db not found., terminating

although in the etc/mongod.config the specified path is /var/lib/mongodb (that's where I was giving all this permissions at) Edit: fixed that with the CMD "do sudo mkdir /data", the repair run its course successfully, but it didn't help me.

so what do I do? how to fix it? how to run the Mongodb?

additional info: I ran it using

sudo service mongod start
