Problems Installing Mongodb on Ubuntu 20.04

Question

Will give a quick context. I was strict to the manual: https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/

wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list
sudo apt-get update
sudo apt-get install -y mongodb-org
sudo systemctl start mongod
sudo systemctl status mongod

● mongod.service - MongoDB Database Server
Loaded: loaded (/lib/systemd/system/mongod.service; enabled; vendor preset: enabled)

mongo

MongoDB shell version v4.4.1
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27017 :: caused by :: Connection refused :
connect@src/mongo/shell/mongo.js:374:17
@(connect):2:6
exception: connect failed
exiting with code 1

Then tried to fix this status=14/n/a with:

sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chown mongodb:mongodb /tmp/mongodb-27017.sock

and other stuff

Then deleted mongodb with:

sudo apt-get purge mongodb-org*
sudo apt remove mongodb
sudo apt purge mongodb
sudo apt autoremove

And install it the same way from above with the same result. I need help.

That's the etc/mongod.conf

Here is the mongod logs from var/log/mongodb/mongod.log the file is 550 liner and I copied only the last log:

Update ATM I tried another reinstall this time with guide from stackoverflow:

sudo apt-get install --reinstall mongodb (had error - Errors were encountered while processing)
sudo systemctl daemon-reload
sudo apt update/upgrate
sudo apt install mongodb (The following package was automatically installed and is no longer required)
sudo apt autoremove
sudo systemctl status mongodb (Main process exited, code=exited, status=100/n/a)
sudo mongo

Now I belive we have working mongod, only to connect it with mongod.service

Ok, I put is in the question, should have done it from beginning. This line bindIp: 127.0.0.1, tried commenting it and bindIp: true at some point — Lyubosumaz, Nov 12 '20 at 11:10
What do you have in your logfile (`/var/log/mongodb/mongod.log`)? — Wernfried Domscheit, Nov 12 '20 at 13:19
Ok, I added a log. `mongod.log` and `mongodb.log` are pretty lengthy so I copied only the last log from `mongod.log` — Lyubosumaz, Nov 12 '20 at 13:50
Have a look at this line: `"An incomplete repair has been detected! This is likely because a repair operation unexpectedly failed before completing. MongoDB will not start up again without --repair.` — Wernfried Domscheit, Nov 12 '20 at 15:30
Ok, that's good to know. I tried command repair at some point and it failed. Sorry for being such a junior. Will add more info to the question. — Lyubosumaz, Nov 12 '20 at 16:13

start with removing all PPA repositories for mongodb, then:

sudo apt-get purge mongodb-org*
sudo apt remove mongodb
sudo apt purge mongodb
sudo apt autoremove
sudo rm -r /var/log/mongodb
sudo rm -r /var/lib/mongodb
sudo apt-get install gnupg
wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list
sudo apt-get update
sudo apt-get upgrade
sudo apt update
sudo apt upgrade
sudo apt-get install -y mongodb-org
sudo apt-get install libc6
sudo service mongod start
sudo service mongod status

This helped me with the issue

Amazing. I have no idea why but this fixed this for me. Thanks! – fIwJlxSzApHEZIl May 01 '21 at 03:42
what's the ppa of mongodb? how do I remove all the PPA? – Skeeith22 Aug 30 '22 at 16:13
Thanks, You helped a lot. "sudo apt-get upgrade" and "sudo apt upgrade" commands are redundant. I suggest to remove them from the answer. – Holtz Ilya Dec 24 '22 at 20:38
I don't know why but this answer also worked for me, even though I've done it many time. I think the difference here is that step 3 6 7 11 12 13 14 16 is not mentioned in the other tutorial or other answers. – fudu Apr 20 '23 at 04:18
also, for someone who stuck with step 9, try to open https://www.mongodb.org/static/pgp/server-4.4.asc in browser, then download it manually, then run `sudo apt-key add server-4.4.asc`. – fudu Apr 20 '23 at 04:19

You are getting this error because you didn't give access to mongodb all you need to do is

sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chown mongodb:mongodb /tmp/mongodb-27017.sock

sudo service mongod restart

you can use this medium.com link,too.

now enjoy working with mongodb

Mongodb server-4.4.asc has a bug for ubuntu 20.04 on some machines. I retry few times and I found a bug on "server-4.4.asc". I advice to install "server-4.2.asc" (ver 4.2 is OK and 4.4 has bug).

see this link: [1]: https://www.howtoforge.com/how-to-install-and-use-mongodb-on-ubuntu-2004/

MongoDB is already included in Ubuntu package repositories, but the official MongoDB repository provides the most up-to-date version and is the recommended way of installing the software. In this step, we will add this official repository to our server.

Ubuntu ensures the authenticity of software packages by verifying that they are signed with GPG keys, so we first have to import the key for the official MongoDB repository.

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 0C49F3730359A14518585931BC711F9BA15703C6

Next, we’ll add MongoDB repository details so apt will know where to download the packages. Issue the following command to create a list file for MongoDB.

echo "deb [ arch=amd64,arm64 ] http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.4.list

Finally, we’ll update the packages list.

sudo apt-get update

We’ll install the mongodb-org meta-package, which includes the daemon, configuration and init scripts, shell, and management tools on the server.

sudo apt-get install mongodb-org

:)
