Once the OS is installed brand new, Please go through the following steps. I just write this for myself.

01. Install Browsers and Sync Data

Firefox, Chrome, Chromium and Sync them. (Make Chrome default)

02. Install Software

I am a developer + tutor. So I need the following things.

Development Software

  1. Terminator (My favorite Terminal)
  2. Postman
  3. VS code (for Angular and Node js)
  4. Sublime
  5. Atom (for Ruby on Rails)


  1. Skype
  2. Teams
  3. Telegram

Recording and Editing

  1. vokoscreenNG (Screen Recording)
  2. Audacity (Audio Editing)
  3. shotcut (Video Editing)

03. Install GIT

sudo apt-get updatesudo apt-get install git

04. Install CURL

sudo apt install curl

05. Adding OH MY ZSH to terminal

sudo apt install zsh


sh -c "$(curl -fsSL"

I use the theme agnoster

Go to

vi ~/.zshrc

This theme needs special fonts, and that is Power-line

sudo apt-get install fonts-powerline

Then it should display like

06. Setup your SSH

I have many git accounts to manage. So I need multiple SSH keys to work with.

to use multiple SSH keys

ssh-keygen -t rsa -C "user1" -f "user1"

Add the SSH accounts in the config

#user1 account
User git
IdentityFile ~/.ssh/user1
IdentitiesOnly yes

#user2 account
User git
IdentityFile ~/.ssh/user2
IdentitiesOnly yes

Add the SSH key to the keychain

ssh-add -K ~/.ssh/user1.rsa

Add the public keys to the GitHub, Git-lab, Bit-bucket accounts

When you use the ssh accounts <-- Remember this please :/

07. Setup the Development Environment for angular

curl -sL | sudo -E bash -
sudo apt-get install -y nodejs
sudo npm install npm@latest -gsudo npm install -g @angular/cli

08. Install tweak-tools

I have the separate monitor at home and I normally use that as my primary workstation. So it is decent to close the lid of the laptop and connect the display via HDMI with the monitor. Tweak-tools help me do that

09. Install Docker and Docker-Compose

10. Install Mongo

Cheers !!!!
