Kaleido:TNG failure using WSL ubuntu 24.04

[gvwilson]

Here is what I tried - I have not been able to make it work so far.

I use Windows 11 + Ubuntu on WSL
WSL ubuntu 20.04 - Does not support GUI applications
WSL ubuntu 22.04 - Supports GUI applications, but its quite buggy
WSL ubuntu 24.04 - Supports GUI applications and chrome

Due to this, I decided to test with WSL ubuntu 24.04 with chromium browser
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 24.04 LTS
Release:        24.04
Codename:       noble
$ chromium-browser --version
Chromium 129.0.6668.100 snap

I get the following error with test.py

This is repeatable - and has never successfully worked for me.

I can see there is an error about kaleidoscopes not defined - so, I tried checking if my chromium works with:
$ chromium-browser
and it opened up fine.

FYI this is chromium reporting a javascript error. I'm going to improve the debugging, install WSL, and debug this myself.

It's probably a path issue.

[ayjayt]

• [ ] Improve debugging options on kaleido, especially in regards to paths to vendored libraries
• [x] Install WSL and see how it goes

[ayjayt]

So @gvwilson AFAIK this should work w/ the new release candidate.

Closed because likely solved
