Need Help with some Software

Hi there,

I have just moved from Arch to NixOS… still getting used to some things, but I got it pretty much setup so far. There are just two problems I have run into.

The first one is the Vivaldi browser. It is not working and crashes with the following error:

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.

[0210/082217.812709:ERROR:elf_dynamic_array_reader.h(64)] tag not found
[0210/082217.812946:ERROR:elf_dynamic_array_reader.h(64)] tag not found
[0210/082217.814426:ERROR:process_memory_range.cc(75)] read out of range
Aborted (core dumped)

I noticed in the wiki, that there is an issue with the current build and it suggests that adding

(vivaldi.overrideAttrs
      (oldAttrs: {
        dontWrapQtApps = false;
        dontPatchELF = true;
        nativeBuildInputs = oldAttrs.nativeBuildInputs ++ [pkgs.kdePackages.wrapQtAppsHook];
      }))

should fix it… so my config looks like this:

environment.systemPackages = with pkgs; [
  vim # Do not forget to add an editor to edit configuration.nix! The Nano editor is also installed by default.
  wget
  htop
  gparted
  brave
  vivaldi
  (vivaldi.overrideAttrs 
        (oldAttrs: {
          dontWrapQtApps = false;
          dontPatchELF = true;
          nativeBuildInputs = oldAttrs.nativeBuildInputs ++ [pkgs.kdePackages.wrapQtAppsHook];
  }))
  lutris
  heroic
  ];

I am not sure, if I applied this correctly, but it does not seem to work. Vivaldi is not launching.

In addition, I got another issue. When I try to install KDE AudioTube, I get the following error:

CMake Error at CMakeLists.txt:52 (message):
  QtMultimedia gstreamer backend not found.  AudioTube only works with the
  gstreamer backend.

I have installed gstreamer plugins, but apparently I am unable to find the right one…

Any help would be appreciated.

Cheers

Hello

there you only need vivaldi.ovverrideAttrs… . The package vivaldi should be deleted.
Second:

Which Audio Tube package have you installed?
https://search.nixos.org/packages?channel=unstable&size=50&sort=relevance&type=packages&query=audiotube

This worked. Thank you!

I have switched from stable to unstable… AudioTube works now… I think for now I am all set and I got most of my stuff running again… Cool acually…

Now I gotta look into garbage collection and remove some of the old packages, I installed originally.

Thanks for your help.
