Hey Spencer!

Some things you can do to test in strict mode is to tail
/var/log/syslog, running your program, and check the apparmor denial you
probably get when acessing to some files/do some calls.
That would be a great hint for you on debugging this issue, and report a
bug if a new interface tweak is needed!

Remember that you won't be able to publish on the stable channel if your
snap is in devmode.

Cheers,
Didier

Ugh...devmode snaps can't be released on the stable channel.

And the devmode snap is probably accessing the outside environment to solve
the problem anyway, which defeats the purpose.

So I don't know how to solve the problem.  If anyone cares to see my crappy
snap-app, it is at...

https://github.com/spencerparkin/ChineseCheckers.git

Enable sound, then hold ALT+SHIFT while doing a left-click in the window to
test sound.

pulseaudio plug/slot

[Spencer Parkin]

Hi,

I'm adding sound-fx to my snap-app and am running into the common problem
of "it works in my real system, but not in the confined system."  I'm not
sure how to trouble-shoot this problem.  I've added the "pulseaudio" plug
to my snapcraft.yaml file, "snap interface" reports that my snap-app is
using the "pulseaudio" plug, I've tried exporting the
"SDL_AUDIODRIVER=pulseaudio" environment variable before running my snap to
make sure that I'm using the appropriate audio back-end.  Hmmm...maybe
snap-apps can't read environment variables?  Maybe I need to configure some
env-vars in my snapcraft.yaml file?  I'll try to see how to setup the
environment (env-vars) for snaps.

Anyhow, I can hear my sound-fx when run on my real system, but not under
unbuntu core.

Thanks for any ideas you may have,

Ubuntu core 16 from 19.09.2016 soes not work on RPI3

[Tomasz Chacuk]

Hello,

I wanted to try new beta from 19.09 on my RPI3, but whenever i try tu burn
the image (Win32Imager) loading hangs just after kernel strts loading - i
get the image of 4 rapbberies on the top of the screen but no further
messages - this hangs forever. I have only HDMI+Ethernet plugged (tried
plogging and unpluggin USB keyboard - no effect)

Will be grateful for info.
