ChromeOS | Linux Development Environment | Install Flatpak onto a Chromebook

• Open the Linux Development Environment menu
• From within the menu select Penguin to open a Linux Terminal windows
• First we are going to check for update by typing:

sudo apt update

• As we did not have any updates, there was no need to perform an update. However, if you need to update the applications and services in your instance of Linux you will need to type:

sudo apt-get dist-upgrade

Notes: After updating Linux, we recommend that you close Linux and reboot your Chromebook before you try and install Flatpak. If you right click on the Terminal icon we place in the Dock, a quick menu will appear giving you the option to shutdown Linux.

• We now need to install Flatpak. To do this we need to type:

sudo apt install flatpak 

• We are now informed as to which packages need to be installed into Linux and asked if we wish to continue.
• If we type Y for yes, when we press enter Flatpak will be installed.
• Flatpak will have been installed onto our Chromebook when we see the command prompt.
