I am on Fedora 38. I am trying to run an AppImage Qt application on Wayland. By default, this doesn’t happen, so I tried
export QT_QPA_PLATFORM=wayland
This then causes the following error: qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in ""
. A common advice on how to handle this error (although found mostly on some Ubuntu-related forums, so maybe the things are slightly different there) is to install the packages qt6-qtwayland and qt5-qtwayland. However, both packages are indeed installed on my system. I have tried reinstalling them, but this didn’t help. Is there anything else I should try?
