In this PC, setting export QT_QPA_PLATFORM=wayland before running the command did nothing, but on my laptop (same OS, but not a clean install as this PC), I got the following info:

no qt platform plugin found message

user@example:~$ spyder --debug-info verbose --debug-output terminal
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
Could not find the Qt platform plugin "wayland" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

Awesome! Thanks so much @juliangilbey and @ccordoba12 .

Thanks @ccordoba12 for your reply; I’m sorry for having missed that! I was in a rush and completely missed your comment, I have added a member of the Debian Science team (listed as maintainers of Ubuntu’s Spyder package) to the relevant bug on Ubuntu’s bug tracker, hopefully this gets Spyder re-packaged.
