Qt Creator online installer for linux: no Qt platform plugin could be initialized

Diracsbracket

Hi
I tried to reinstall Qt Creator on my Debian 10 VM and got this error upon launching the installer:

buster@buster:~/Downloads$ ./qt-unified-linux-x64-online.run
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
qt.qpa.plugin: 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: minimal, xcb.

Aborted
buster@buster:~/Downloads$

The Qt installer complaining that it cannot find a Qt plugin???

Well, it's a Qt app :-)
Are you running Wayland on your VM?

Hi @jsulm ,
Apparenltly yes:

echo $XDG_SESSION_TYPE
wayland

I also tried with Gnome Classic desktop, where the above echo returns x11, but still got the same error.

Found the problem.
There was still an environment variable set in my .bashrc

QT_QPA_PLATFORM=wayland

Removed it and it worked...
