Problem Description

I tried launching Spyder from a fresh Anaconda install, but it crashed almost immediately upon launching. I'm not too sure how to interpret the error message I got, and how to solve it. Would appreciate some advice on this, thank you!

What steps reproduce the problem?

1. installed X11 for WSL
2. append the following to .bashrc file
   DISPLAY=:0
   export DISPLAY
   LIBGL_ALWAYS_INDIRECT=1
   Export LIBGL_ALWAYS_INDIRECT
3. installed Anaconda 2020.02 on Ubuntu 20.04 LTS
4. launch spyder

What is the expected output? What do you see instead?

I see the spyder start-up screen that says 'initialising', but then it crashes almost soon after and I see the following error message.

Hi @angrosamund, thanks for the report.

We currently do not provide testing on WSL on Linux so things are most likely not going to work in the setup you describe.
