Looks like we need to limit this to classic (via system:) if we apt here.

[fgimenez]

@mvo5 indeed, very good catch, thanks!

@niemeyer thanks, i've added a specific upstart job for 14.04, please take another look.

@fgimenez I think you need to build and upload a ppc64el version of this snap:

+ snap install --edge test-snapd-dbus-provider
error: cannot install "test-snapd-dbus-provider": snap not found

[fgimenez]

@zyga thanks! the tests snaps are already in place

[mvo5]

Looks good, one question inline.

[mvo5]

The usual way to do this (as documented in the man-page) is eval $(dbus-launch --sh-syntax) - is this not working for some reason?

[fgimenez]

@mvo5 exactly, when using eval $(dbus-launch --sh-syntax) I get:

+ sleep 1
+ MATCH 'hello world'
+ dbus-send --print-reply --dest=com.dbustest.HelloWorld /com/dbustest/HelloWorld com.dbustest.HelloWorld.SayHello
Failed to open connection to "session" message bus: /usr/bin/dbus-launch terminated abnormally with the following error: Autolaunch error: X11 initialization failed.

error: pattern not found, got:

+ sleep 1
+ MATCH 'hello world'
+ dbus-send --print-reply --dest=com.dbustest.HelloWorld /com/dbustest/HelloWorld com.dbustest.HelloWorld.SayHello
Failed to open connection to "session" message bus: /usr/bin/dbus-launch terminated abnormally with the following error: Autolaunch error: X11 initialization failed.
