No response of click on systray icon.

[twang2218]

If the snap is installed in the devmode, everything works correctly, however, if it's installed in strict/dangerouse, the systray icon is not working correctly.

Installed in devmode

sudo snap install --devmode ./qqmusic_1.1.1_amd64.snap

Verify the mode:

➜ snap info --verbose qqmusic

And the systray icon works correctly.

Installed in strict/dangerous mode

sudo snap install --dangerous ./qqmusic_1.1.1_amd64.snap

The mode can be verified by CLI:

And nothing happened if click on the qqmusic systray icon.

Problem

The bluez error should not be the problem, I can overcome it by connecting it to bluez interface, and the result is the same.

The following error caught my eyes, and I'm not sure whether it's the cause of the problem:

stderr: dbus-monitor: unable to enable new-style monitoring: org.freedesktop.DBus.Error.AccessDenied: "An AppArmor policy prevents this sender from sending this message to this recipient; type="method_call", sender=":1.18543" (uid=1000 pid=501935 comm="dbus-monitor --session type='signal',interface='or" label="snap.qqmusic.qqmusic (enforce)") interface="org.freedesktop.DBus.Monitoring" member="BecomeMonitor" error name="(unset)" requested_reply="0" destination="org.freedesktop.DBus" (bus)". Falling back to eavesdropping.

[twang2218]

Raised the problem in snapcraft.io (https://forum.snapcraft.io/t/trouble-to-get-electron-apps-systray-icon-working-as-a-snap/26623)

[twang2218]

Current workaround of the problem, fix the AppArmor profiles by provided script:

sudo /snap/qqmusic-snap/current/fix-tray.sh

The script fix-tray.sh will patch and reload the AppArmor profile for qqmusic-snap. Relaunch the qqmusic-snap, the systray should work correctly.

[twang2218]

Update:

I send the pull request: snapcore/snapd#10873 at 2nd Oct, and it's been merged at 18 Oct, it's marked to be part of snapd 2.53. So, the fix-tray.sh workaround will not be necessary after the release of 2.53.
