I found the solution:

npm install -g taiko --unsafe-perm --allow-root

Just need to change openBrowser to

await openBrowser ({
         args: [
             '--no-sandbox'
         ]
     });

Yes, there are a few more options you might want to use which are specified here https://docs.taiko.dev/frequently_asked_questions/#how-do-i-launch-chrome-in-sandbox-mode-on-headless-environments%3F

The original command npx taiko might not work on ubuntu unless it's installed as a non root user. You can set a custom location for the npm library
