3.6.1 not opening on Ubuntu 25.04

[hellocatfood]

I tried opening version 3.6.1 on Ubuntu 25.04 and it crashes with the following error:

ossia-score
ossia score: starting in failsafe mode
QVariant::load: unknown user type with name TimeVal.
qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Aborted

I'm using Gnome 48 with Wayland, NVIDIA GeForce RTX 3050 Ti Laptop GPU

Heya! Thanks, I think that's a Wayland issue ? Can you try to force QT_QPA_PLATFORM=xcb ?

[hellocatfood]

I tried running QT_QPA_PLATFORM=xcb ossia-score but still got the same error.

[jcelerier]

Hmm is that with the .deb package, the appimage or the flatpak?

[hellocatfood]

With the deb package. The appimage seems to work fine but I haven't tried the flatpak

[jcelerier]

okay thanks! I think I see the issue, I'll try something quickly

[jcelerier]

in the meantime I'd recommend using the appimage which is the "official" release, the .deb are honestly not often tested
