Okular does not opens (flatpak)

[aquaspy]

Well, not sure if there is some incompatibility in void linux, but there is something making it impossible to use okular flatpak here.

Every time I try to open it I get an error:

Any ideas about this? Thanks!

[tsdgeos]

Interesting, can you please give us details of your system?

i.e. which distribution, etc.

[Erick555]

I see void linux in description (this one)

[tsdgeos]

Ah right, missed that.

Can you please past the contents of flatpak list ?

[aquaspy]

Of course!

I think KDE dependencies are ok

[tsdgeos]

Looks reasonable.

Can you do this?
flatpak run --command=sh --devel org.kde.okular
gdb -ex run /app/bin/okular-bin

it will hopefully crash, then type bt and paste the output of bt

[aquaspy]

flatpak run --command=sh --devel org.kde.okular
gdb -ex run /app/bin/okular-bin

I won't even crash I guess. I think I need to install kde sdk?

[aquaspy]

Ok Im installing

[aquaspy]

Sadly, even after the install, the error still the same

[Erick555]

Could you show flatpak run -vvv org.kde .okular?

Do you use musl?

[aquaspy]

I use glibc version of void, so no musl fault I guess.

[Erick555]

Do you have pulseaudio and xdg-desktop-portal-{kde/gtk} installed? https://docs.voidlinux.org/config/external-applications.html#flatpak

[aquaspy]

Do you have pulseaudio and xdg-desktop-portal-{kde/gtk} installed? https://docs.voidlinux.org/config/external-applications.html#flatpak

Yes, xdg-desktop-portal for both gtk and kde are installed. Pulseaudio is too. I still not sure on what is causing this.

Does this flatpak depends on opnssl?

[Erick555]

You shouldn't need both gtk and kde portal unless you use multiple DE interchangeably. Flatpak apps have own openssl and everything else they need however I'm not sure if the crash doesn't happen in flatpak itself before real app was started.

[tsdgeos]

Which flatpak version are you running?

[aquaspy]

Flatpak 1.6.3

Which flatpak version are you running?

[aquaspy]

oh, got it. Sadly, I don't know what is the issue then.

[tsdgeos]

Ok, invoking @alexlarsson now.

Any idea why if would crash when doing flatpak run --command=sh --devel org.kde.okular

Seems like it's flatpak itself crashing? See https://user-images.githubusercontent.com/49214136/86306824-92a1b000-bbeb-11ea-93aa-f22f0e315d60.png

@tsdgeos I am not on void linux anymore, just switched to artix with runit. I installed okular from here to test and seems to work perfectly. Maybe a void issue?

[tsdgeos]

Yes, Void was always the suspect either because they do something wrong or because their weirdness makes flatpak crash

I'm having a similar problem. I'm on a chromebook, using the linux on chromeos. I installed okular with flatpak and it doesn't launch. When I click on the icon it starts like if it was going to load, but then never finishes, not erros given. I uninstalled and installed with apt-get and then it worked perfectly.

[AmamosV]

Update: reinstalled okular with flatpak and tried to use the run command instead of the chromebook's icon to see what it would turn out. That's what i got:

$ flatpak run org.kde.okular
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" 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, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

I also use several other apps on linux in my chromebook and they are all working fine with flatpak, just getting this on okular.

Thanks
