On WebKitGTK we are EOL-ing Ubuntu 20.04 so we will like to start using Ubuntu 22.04 as baseline to provide the built products at https://webkitgtk.org/built-products/x86_64/release/nightly/

Can we just skip 22.04 and upgrade to Ubuntu-24.04 ?

I'd certainly be open to a PR trying 24.04. I think Wayland-by-default might cause some issues?

My experience with wayland running on headless servers (no GPU) is that it doesn't work very well with accelerated/opengl content. On the build.webkit.org webkitgtk bots we still run the tests under xvfb due to that, we tested wayland but it was regressing the accelerated/opengl layout tests when the system didn't had a GPU (headless).

But it has been a while (years) since I tried that, perhaps new versions of Weston or other Wayland compositors have improved the status quo.

In any case I would suggest doing this in two steps to be able to blame regressions on either the update of the system, or on the update of the display server.

So first step: update the base system and check for regressions. Then second step: switch to wayland and check for regressions.

Anyway, we are switching the webkitgtk_minibrowser bundles to use an universal bundle with all the required system libraries inside that in theory should work on any distro so we would not longer depend on which version of Ubuntu or any other distro is used on the test container. See: #48698

This is becoming more urgent due to actions/runner-images#11101.
