Blank screen after install

[cjsmocjsmo]

After installing the snap package on my raspberry pi 4 (arm64), and launching it with the desktop icon all i get is a blank screen, no controls nothing just a blank screen.

Ubuntu 23.04

@cjsmocjsmo Hi 👋 when you have time could you refresh the snap and check if this is fixed?

[cjsmocjsmo]

Sure :)

Performed: sudo snap refresh musicpod

Launched the application with the desktop icon and this is what I get:

snap info musicpod name: musicpod summary: Music, podcast and internet radio player publisher: Frederik Feichtmeier store-url: https://snapcraft.io/musicpod contact: https://github.com/ubuntu-flutter-community/musicpod license: MPL-2.0 description: | Play local audio files, browse podcasts online or listen to internet radio stations.

The podcast and radio features do currently need internet access and thus the network-manager-observe permission is being used to display a disconnect from the internet in the user interface. commands:

FYI on my x_86 machine musicpod installs and launches with no issues, so this is exclusive to the arm64 arch :)

Interesting! Thank you very much for investigating

@kenvandine do you have any hint what this needs to run on arm?

[cjsmocjsmo]

Not sure this will help but it satisfied my curiosity. I cloned the musicpod repo and did: cd musicpod flutter run

[Feichtmeier]

aha! yes very useful this means that it is rather related to flutters arm support I thought they merged the arm fix 🤔 But eventually I need to either upgrade or use the dev channel

because this

ERROR: - RenderObjectWidget.createElement
ERROR: - Widget.createElement
ERROR: Try to either
ERROR: - provide an implementation,
ERROR: - inherit an implementation from a superclass or mixin,
ERROR: - mark the class as abstract, or
ERROR: - provide a 'noSuchMethod' implementation.

is weird

[Feichtmeier]

@Jupi007 do you have any under circumstances access to an ARM machine? Looks like our yaru widgets miss some implementations for ARM if I understand this correctly 🤔 ❓

[Jupi007]

@Feichtmeier sorry I only have x64 machines at home. But I think @madsrh got a mac apple silicon.

[Feichtmeier]

@cjsmocjsmo by any chance.... does the issue still happen?

[madsrh]

But I think madsrh got a mac apple silicon

Sorry for the (extremely) slow reply. I'm running the snap and it works just fine here. This is on the M1, I haven't tried the Pi.

[cjsmocjsmo]

My SD card crapped out and had to do a fresh system install (to include musicpod) and this is the results

Ubuntu 23.04 RPI 4 musicpod 0+git.393a6c7 286 latest/edge frederik-feichtmeier

[Feichtmeier]

Okay gonna emulate an ARM machine with qemu and see what's happening

[Feichtmeier]

@cjsmocjsmo sorry for the slow progress on the ARM problem, but I still did not manage to setup this with qemu. I fear I need to buy some sort of ARM machine for this.

I made a build with snapcraft online builds. If you have time would appreciate if you could test the new build from stable or edge, should be an update for your architecture

[cjsmocjsmo]

Hey Frederik nice to hear from you again. Sorry for the slow response, I'm neck deep in a rust project I'm working on, but yea I should be able to test the new package for you this weekend.

FYI complete RaspberryPi kits $169 USD on amazon.

Ubuntu 23.04 musicpod 0+git.5096fdf 533 latest/edge frederik-feichtmeier -

Sadly still the same blank screen. Works great on my x86 machine.

[popey]

Musicpod works fine on arm64 here. (although I should file a bug for the weird squares, i guess).

I'm using revision 533 from the stable channel.

Thanks @popey

This is great news

The characters missing is text where I used emojis.. Eventually for some reason fonts in flutter have an emoji problem on arm? Could you check for example when you troll the search in radio and podcasts when you search for nonsense it should also show a page with emojis

[Feichtmeier]

I can not confirm this it runs fine on arm
