My Question or Issue

Hello Spotify penguins 🙂

I installed Spotify version "1.0.94.262.g3d5c231c-9" via snap without problem.

Spotify is working properly but among the error messages of the application, three errors come back tirelessly when I run it from the command line and I can not solve:
[1223 / 121936.390236: ERROR: object_proxy.cc (616)] Failed to call method: org.freedesktop.DBus.Properties.Get: object_path = / org / freedesktop / UPower: org.freedesktop.DBus.Error.AccessDenied: An AppArmor policy avoids this sender from sending this message to this recipient; type = "method_call", sender = ": 1.68" (uid = 1000 pid = 1720 comm = "/ snap / spotify / 28 / usr / share / spotify / spotify" label = "snap.spotify.spotify (enforce)") interface = "org.freedesktop.DBus.Properties" member = "Get" error name = "(unset)" requested_reply = "0" destination = "org.freedesktop.UPower" (uid = 0 pid = 1325 comm = "/ usr / lib / upower / upowerd "label =" unconfined ")
[1223 / 121936.390499: ERROR: object_proxy.cc (616)] Failed to call method: org.freedesktop.UPower.GetDisplayDevice: object_path = / org / freedesktop / UPower: org.freedesktop.DBus.Error.AccessDenied: An AppArmor policy prevents this sender from sending this message to this recipient; type = "method_call", sender = ": 1.68" (uid = 1000 pid = 1720 comm = "/ snap / spotify / 28 / usr / share / spotify / spotify" label = "snap.spotify.spotify (enforce)") interface = "org.freedesktop.UPower" member = "GetDisplayDevice" error name = "(unset)" requested_reply = "0" destination = "org.freedesktop.UPower" (uid = 0 pid = 1325 comm = "/ usr / lib / upower / upowerd "label =" unconfined ")

Nothing very dramatic but it seems to me that this snap version lacks the support of access rights to UPower. can you help me solve this problem? do you see the same problem?

Thank you in advance for your assistance. Have a good holiday 🙂
