I have tried all the available solutions and unfortunately they are not working for me. I am using ubuntu 20.04

Answer 1

Just run the following commands in ubuntu 20.04:
sudo systemctl start mongod
Then run:
mongod --fork --logpath /var/log/mongodb/mongodb.log --auth --port 27017 --dbpath /var/lib/mongodb
Then run:
mongo
And it worked for me.

Answer 2

Make sure you have entered this command :
sudo systemctl start mongodb
Because I was checking status without staring the mogodb start script

Answer 3

I had a problem installing MongoDB on Ubuntu 21.10, after following the steps outlined in the official documentation I got the same error as the O.P. The following steps worked for me (reboot required)
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10</span>
echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.4.list
sudo apt-get update
sudo apt-get install -y mongodb-org
sudo apt-get install -y mongodb-org=3.4 mongodb-org-server=3.4 mongodb-org-shell=3.4 mongodb-org-mongos=3.4 mongodb-org-tools=3.4
Then open the following with an editor (VIM in this case - use :wq to write and quit)
sudo vim /etc/systemd/system/mongodb.service
Paste :-
#Unit contains the dependencies to be satisfied before the service is started.
[Unit]
Description=MongoDB Database
After=network.target
Documentation=https://docs.mongodb.org/manual
# Service tells systemd, how the service should be started.
# Key `User` specifies that the server will run under the mongodb user and
# `ExecStart` defines the startup command for MongoDB server.
[Service]
User=mongodb
Group=mongodb
ExecStart=/usr/bin/mongod --quiet --config /etc/mongod.conf
# Install tells systemd when the service should be automatically started.
# `multi-user.target` means the server will be automatically started during boot.
[Install]
WantedBy=multi-user.target
Then continue with a reload and a start..
systemctl daemon-reload
sudo systemctl start mongodb
You might just need a reboot after all that... Check status and enable with the following:
sudo systemctl status mongodb
sudo systemctl enable mongodb
