Problems installing and running on Ubuntu 20.04

Ops and Admin
1

I followed steps on https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/

I faced first problem with GPG Key that returns “gpg: no valid OpenPGP data found.”
Somehow I got PUBkey in apt-key list but wget command still returns “no valid”.

After I installed mongodb-org alright.

My systemctl status is always

Active:failed with --config /etc/mongod.conf (code=exited, status=14).

And this is a log after i run "sw@sw-pc  ~  mongod "

Hi @SEUNGWOON_JEON, check if you have proper permission on /tmp directory. Below error seems issue with permission.

{“t”:{"$date":“2021-04-12T09:52:34.638+09:00”},“s”:“E”, “c”:“NETWORK”, “id”:23024, “ctx”:“initandlisten”,“msg”:“Failed to unlink socket file”,“attr”:{“path”:"/tmp/mongodb-27017.sock",“error”:“Operation not permitted”}}

Hi @ROHIT_KHURANA. Thanks for your kindness.
I think I just fixed my problem by uninstall every mongodb related stuff in my computer then re-install from scratch.
It took me 20 hours of doing anything I found on Internet which including giving permission.
Seems like status is Active now (which is better than so far). But I see same issue with permission on log so I will work on it. Thank you.
