Hello.

This post is a continuation of the post on debugging a KaiOS device with Web IDE, but instead of using macOS, you can now use Chrome OS (m75) with Crostini. I'm cribbing from the KaiOS Environment Setup which is a good start, but not enough for getting going with Chrome OS and Crostini. Below is the rough guide that I followed. Make sure that you are using at least Chrome OS m75 (currently dev channel as of April 15th), then:

Ruth John moved to Chrome OS (temporarily): The first thing, and possibly the thing with the least amount of up to date information out there, was enabling Crostini. This runs Linux in a container on the Chromebook, something you pretty much want straight away after spending 15 minutes on it. I have the most recent Pixel, the 256GB version. Here's what you do. Go to settings. Click on the hamburger menu (top left) - right at the bottom it says 'About Chrome OS' Open this and there's an option to put your machine into dev mode It'll restart and you'll be in dev mode - this is much like running Canary over Chrome and possibly turning on a couple of flags.
