MongoDB may fail in Ubuntu 18.04 as of 7/10/2018, to fix it, follow the guide from Mongo official site.
Step 1:
`$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 9DA31620334BD75D9DCB49F368818C72E52529D4`
Step 2:
`$ echo "deb [ arch=amd64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.0.list`
Step 3:
`$ sudo apt-get update`
Step 4:
`$ sudo apt-get install -y mongodb-org=4.0.2 mongodb-org-server=4.0.2 mongodb-org-shell=4.0.2 mongodb-org-mongos=4.0.2 mongodb-org-tools=4.0.2`
Step 5:
`$ sudo service mongod start`
Step 6:
```
$ sudo service mongod status

- NodeJS and NPM may fail in Ubuntu 18.04 as of 7/10/2018, to fix it:
Step 1 - Try remove the npm first:
```
$ sudo apt-get remove nodejs
$ sudo apt-get remove npm
```
Check if npm or node folder still exist, delete it if you found them
```
$ which node
$ which npm
```
Step 2 - reinstall NodeJS:
```
$ curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
$ sudo apt-get install -y nodejs
```
Check if npm and node was installed and you're ready to use node.js
```
$ node -v
$ npm -v
```
