Description
On Ubuntu 22.04.
When logging in, software updater told me I could update albert, which I did. Since then, I cannot launch it.
I tried to reinstall it (sudo apt remove, then install), same result. Ran apt update to check if dependences were missing, but nope. However, I could further apt upgrade albert from 0.18.0-0 to 0.18.1-0.
It seems like a silly error, I tried to look it up and found different things like "revert to Xorg" or running it with options (like -platform=wayland) but same result.

Expected behavior
Launch normally when I run it.

Steps to reproduce
Run albert.

Output of `albert --report ` Same as below, can't even check the version.
Output of `albert` when started in a terminal (stdout/stderr) 
[warn:albert] Application has not been terminated graciously
 [info:default] Warning: Ignoring WAYLAND_DISPLAY on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
 [warn:qt.qpa.plugin] Could not find the Qt platform plugin "xcb" in ""

[fatal:default] This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Oh, it actually removed the line [warn:qt.qpa.plugin] Could not find the Qt platform plugin "xcb" in "". However, the rest stays the same.

Maybe some of the tips in #958 may help. I sense that the hotkey/xlib makes problems again.

Does installing this package help?

No, I have that installed already. (reinstalling does not help either).

Installing qt6-wayland solved this issue for me in a vm. Please confirm dudes, because I installed a lot of other packages. I changed this dep in the repo. I hope this fixes this one. Unforunately this still ends up in #1148

The new packages containing the qt6-wayland dependencies are build and published. I am not sure if OBS gives packages a revision. Maybe you have to reinstall it.

I did apt-get upgrade that install a new version and install the qt6-wayland the output changed but still don't work :

I tried to sudo apt install qt6-gtk-platformtheme and got qt6-gtk-platformtheme is already the newest version (6.2.4+dfsg-2ubuntu1)., which doesn't seem to be the latest version from your link to qt6-wayland (6.3.1+dfsg-10 and others) .

I was prepared to try to install it manually, but before that, I once again tried to sudo update and there was a new update available for albert albert/unknown 0.18.1-0 amd64 [upgradable from: 0.18.1-0].. This seemed to do the trick by installing the following packages:

The following NEW packages will be installed
  libqt6opengl6 libqt6qml6 libqt6qmlmodels6 libqt6quick6 libqt6waylandclient6
  libqt6waylandcompositor6 libqt6waylandeglclienthwintegration6
  libqt6waylandeglcompositorhwintegration6 libqt6wlshellintegration6
  qt6-wayland
The following packages will be upgraded:
  albert

The error is now the same as 1148.

Yes I changed the dependencies. The package is different. Unfortunately OBS does not increase the version suffix. Obviously you have to reinstall it

This issue should be solved with the recent updates right?

I failed now to #1148 with latest package.

I find that I observe after the installation:

The following packages were automatically installed and are no longer required:
  libts0 qt6-qpa-plugins

So I deleted the package, then I start albert

$ albert 
21:06:54 [warn:albert] Application has not been terminated graciously

I've the feeling that one of the 2 packages are mandatory.

Now going to #1148 😄
