How to setup & install oh my zsh on Chrome OS

A guide to setup and install oh my zsh with agnoster theme and working fonts like a pro on Chrome OS.

agnoster on Chromebooks

First Things first! Turn on Linux.

At the time of writing this, Linux on Chromebooks is in beta. To turn it on, head over to Settings, under Linux (beta) click on Turn On. It will take some time to install Linux.


Set sudo password

By default Linux on Chrome OS doesn’t come with a password for sudo, we will set one up, as it is required to set zsh as the default shell.

$ sudo su
$ passwd pushp.vashisht

Remember to change pushp.vashisht with your username. You will be prompted for password, provide one.

Install zsh and Oh my zsh

$ sudo apt install zsh
$ chsh -s $(which zsh)
$ sudo apt install wget git
$ wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh
$ cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc
$ source ~/.zshrc
$ vi ~/.zshrc

Change the ‘ZSH_THEME’ line 10 with ‘agnoster’ theme as below:

ZSH_THEME='agnoster'

Save & exit.

$ source ~/.zshrc

Done! Oh my zsh is installed. Uh-Oh! the fonts aren’t getting displayed correctly as some of the symbols are missing. On any Linux distro installing powerline font via apt would have solved the problem, but, here it won’t.

Configuring custom font

Open a tab in chrome and hit `Ctrl + Alt + t`, a new tab with crosh will open up. Now, hit `Ctrl + Shift + p`, a new tab with Terminal settings will open up.

terminal settings example
  1. Enter https://cdn.jsdelivr.net/gh/wernight/[email protected]/PowerlineFonts.css in front of Custom CSS (URI)
  2. Enter “Hack” before ”DejaVu Sans Mono” in front of Text Font Family like: “Hack”, ”DejaVu Sans Mono”

Now, head back to your Linux terminal and you should see the fonts getting displayed properly.

If the fonts are still not displayed correctly

  1. Open your Linux terminal
  2. Under text change font to ‘Source Code Pro, as shown below:
source code pro

Now, the font should be working as expected!
