For further digging I found An appArmor policy prevents from webapp-container expose MPRIS signal time=1764940153.079286 sender=:1.134 -> destination=(null destination) serial=19 path=/org/mpris/MediaPlayer2; interface=org.freedesktop.DBus.Properties; member=PropertiesChanged string "org.mpris.MediaPlayer2.Player" array [ dict entry( string "PlaybackStatus" variant string "Paused" ) ] array [ ] error time=1764940153.079343 sender=org.freedesktop.DBus -> destination=:1.134 error_name=org.freedesktop.DBus.Error.AccessDenied reply_serial=19 string "An AppArmor policy prevents this sender from sending this message to this recipient; type="signal", sender=":1.134" (uid=32011 pid=19620 comm="youtube-web" label="youtube-web.mateo-salta_youtube-web_7 (enforce)") interface="org.freedesktop.DBus.Properties" member="PropertiesChanged" error name="(unset)" requested_reply="0" destination="org.freedesktop.DBus" (uid=32011 pid=15732 comm="/usr/bin/mpris-proxy" label="unconfined")" method call time=1764940153.084393 sender=:1.141 -> destination=org.freedesktop.DBus serial=8 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=RemoveMatch string "type='signal', path='/org/freedesktop/DBus/Local',interface='org.freedesktop.DBus.Local', member='Disconnected'" method return time=1764940153.084439 sender=org.freedesktop.DBus -> destination=:1.141 serial=9 reply_serial=8 is there any way we can configure app mirror policy ?

@neinei0612 I'm sorry, that is outside of the scope of this forum.

@uxes That is a great program, but I heard that ATL relies on GTK. Which is not integrated into UT. And besides, list of supported apps is limited compared to Waydroid.

@uxes Dobrý nápad

@sermountain I see many occurences of this kind of problem on the Github site, such as https://github.com/ubports/ubports-installer/issues/2412 the reference in this post is on this forum and then it goes to a blog post (here: https://rubencarneiro.github.io/rubencarneiro.io//Volla-phone-Repair/) that links itself to a Mediatek flash tool that is reported to work. It's complicated, however I can't directly help you I have a Fairphone myself. Good luck.
