Failed to register: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied

Hello everybody,

I’m trying to have my app made with flutter available on snapstore (test app for now).
The app works good when launched directly by flutter, and I can compile and push the snap to the store.
But after installing it, I got this error when I want to launch it “Failed to register: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Connection “:1.177” is not allowed to own the service “com.shanuy.sasomtam” due to AppArmor policy”

Here is my yaml file :

name: sasomtam
version: 0.1.2
summary: Card rewards system
description: Card rewards system

confinement: strict
base: core18
grade: stable

apps:
sasomtam:
command: sasomtam
extensions: [flutter-master]
plugs:
- network

parts:
sasomtam:
source: .
plugin: flutter
flutter-target: lib/main.dart # The main entry-point file of the application

thank you by advance!

You need to add and configure a slot for your dbus service:

slots:
  dbus-sasomtam:
    interface: dbus
    bus: session
    name: com.shanuy.sasomtam

apps:
  sasomtam:
    ... # the rest of your app definition
    slots:
      - dbus-sasomtam

Hi Daniel,
I faced the same issue with one of my builds today.
The link to my snapcraft.yaml is here :

github.com

keshavbhatt/gtkmm-test-snap/blob/main/snap/snapcraft.yaml

name: gtkmm-test # you probably want to 'snapcraft register <name>'
base: core18 # the base snap is the execution environment for this snap
version: '0.1' # just for humans, typically '1.2+git' or '1.3.2'
summary: simple gtk+ test app # 79 char long summary
description: |
  This is my-snap's description. You have a paragraph or two to tell the
  most important story about your snap. Keep it under 100 words though,
  we live in tweetspace and your description wants to look good in the snap
  store.

grade: stable # must be 'stable' to release into candidate/stable channels
confinement: strict # use 'strict' once you have the right plugs and slots
architectures:
       - amd64
environment:
  SNAP_DESKTOP_RUNTIME: $SNAP/gnome-platform
  GTK_USE_PORTALS: '1'

apps:
   kite:

I added the slots declaration in the recipe and now my snap has to go through manual-review before getting released.

I am also getting these error when am running the app:

(process:28831): Gtk-WARNING **: 16:49:14.204: Locale not supported by C library.
	Using the fallback 'C' locale.

This likely means that your installation is broken.
Try running the command
  gdk-pixbuf-query-loaders > /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache
to make things work again for the time being.
