unity7 interface does not work with libnotify

[Pavel Rojtberg]

using libnotify through gir1.2-notify-0.7 I get the following error:

GLib.Error: g-dbus-error-quark: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: An AppArmor policy prevents this sender from sending this message to this recipient; type="method_call", sender=":1.160" (uid=1000 pid=24558 comm="python3 /snap/teatime/x2/usr/share/teatime/teatime") interface="org.freedesktop.Notifications" member="GetServerInformation" error name="(unset)" requested_reply="0" destination=":1.142" (uid=1000 pid=15532 comm="/usr/lib/x86_64-linux-gnu/notify-osd ") (9)

snap works if installed with --devmode.

Thank you for reporting a bug. Can you please provide steps to reproduce? (eg, a snapcraft.yaml file or a snap). Thanks!

what version of snapd do you have installed?

[Pavel Rojtberg (rojtberg)]

2.0.10

[Sebastien Bacher (seb128)]

weird, it should work with that version and it works on my system...

[Pavel Rojtberg (rojtberg)]

did you try to build the teatime snap? if so the error only occurs once a timer finishes, since it only then tries to display a notification.

[Jamie Strandboge (jdstrand)]

If I do:
$ sudo snap install teatime

then launch with:
$ teatime

I see:
** (process:28769): WARNING **: Failed to load shared library 'libunity.so.9' referenced by the typelib: libunity-protocol-private.so.0: cannot open shared object file: No such file or directory
**
ERROR:../../gi/gimodule.c:426:_wrap_pyg_hook_up_vfunc_implementation: assertion failed: (G_TYPE_IS_CLASSED (implementor_gtype))

and this denial:

Is this the teatime I should be testing?

[Jamie Strandboge (jdstrand)]

I'm going to attempt https://launchpad.net/~rojtberg/+snap/teatime/+build/1819/+files/teatime_16.07_amd64.snap.

[Jamie Strandboge (jdstrand)]

https://launchpad.net/~rojtberg/+snap/teatime/+build/1819/+files/teatime_16.07_amd64.snap had the same problem. Can you provide a working snap or otherwise give the exact steps to reproduce?

[Jamie Strandboge (jdstrand)]

I gave it one more try and did:

$ git clone git://git.launchpad.net/teatime
$ cd ./teatime
$ snapcraft
$ sudo snap install ./teatime_16.07_amd64.snap
$ teatime

This time it doesn't crash (I guess the launchpad buildd's don't have an up to date snapcraft? </guess>).

I can now confirm the apparmor denial,

[Sebastien Bacher (seb128)]

Thanks Jamie, I was going to try to build the snap now but looks like you beat me to it. I had tried with a command line and gdbus send the other day which worked, I guess the code is doing something different there...

[Pavel Rojtberg (rojtberg)]

mind sharing the commit? I would be intrested in the fix.

[Pavel Rojtberg (rojtberg)]

but when is this going to be deployed?

[Jamie Strandboge (jdstrand)]

This is fixed in 2.12 upstream and 2.12+0.16.04 in Ubuntu 16.04.
