Apt-get fails on 16.04 or 18.04 installing mongodb
Ubuntu 16.04 and MongoDB 4.0
First, remove any existing repository file for MongoDB.
sudo rm /etc/apt/sources.list.d/mongodb*.list
Next, add the key: (without the key, the repository will not load)
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv E52529D4
Now, create a new MongoDB repository list file:
sudo bash -c 'echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/4.0 multiverse" > /etc/apt/sources.list.d/mongodb-org-4.0.list'
Complete the installation with update of repositories then install:
sudo apt update
sudo apt install mongodb-org
Enable the mongod service and start it up:
systemctl enable mongod.service
systemctl start mongod.service
Check your mongodb version:
~$ mongo --version

Hope this helps!
In addition to @Terrance 's answer, here is how you can find appropriate sig key. Example is applicable to mongodb in this case but can be used for any other package similarly. Before you execute lines from @Terrance 's answer:
Go to ubuntu key server to find actual key
Search for string of interest (mongodb in case) and submit that first form (you don't need second form for this) - click
Search!button
- On provided search list seek for your version (it was 3.4 in my case here in example)
You can see two rows with keys there. Focus on most actual by date. First string is date created while second one is date valid due.
Use sig from row mentioned in point 5 - in case from picture it would be
A15703C6Continue with Terrance 's answer wether you need to install package or upgrade like myself
First run:
$ sudo rm /etc/apt/sources.list.d/mongodb*.list
It would be recommended to also remove any lines that are related to MongoDB from the /etc/apt/sources.list file.
Then do a fresh installation of MongoDB using the commands provided in the official MongoDB intstallation instructions for Ubuntu.
Commands in provided link are given below

sudo apt-get install gnupg

sudo apt-get update
sudo apt-get install -y mongodb-org
sudo service mongod start
sudo service mongod status
