I just installed Qt Creator, and then I launch like this:
lz@vm:~/Qt/Tools/QtCreator/bin$ ./qtcreator
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/usr/lib/x86_64-linux-gnu/qt5/plugins/platforms" even though it was found.
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.
I tried things like here: "Failed to load platform plugin "xcb" " while launching qt5 app on linux without qt installed but they assume you're trying to launch your own compiled qt app. I'm trying to launch the qt creator
UPDATE:
lz@vm:~/Qt/Tools/QtCreator/bin$ QT_DEBUG_PLUGINS=1 ./qtcreator
