Thanks for the report. I'm unable to reproduce. Are you running X, or Wayland? Anything unusual about your setup? Do other graphical snaps work in your env? E.g. most snaps featured at https://snapcraft.io/store are high-profile GUI apps.
Please help me debug by providing the following info about your environment:
snap info moonlight
snap version
echo $XDG_SESSION_TYPE
echo $DISPLAY
glxgears # just double checking
And let's run a few commands inside the snap container as well:
snap run --shell moonlight
(snap)$ source $SNAP/snap/command-chain/snapcraft-runner # setup snap env, PATH, etc
(snap)$ echo $XDG_SESSION_TYPE # value should be same as above
(snap)$ echo $DISPLAY # value should be same as above
(snap)$ glxgears # this should work

Thanks. Are you able to run any other snap with a GUI?

Same issue here. Using Lubuntu 18.10 with Intel HD Graphics 620 (rev 02).
I checked Foobillard-plus Snap - works like a charme.
If you need more details, let me know.

Hm, are all interfaces connected?
$ snap interfaces moonlight
Slot Plug
:desktop moonlight
:desktop-legacy moonlight
:home moonlight
:joystick moonlight
:network moonlight
:network-manager moonlight
:opengl moonlight
:pulseaudio moonlight
:screen-inhibit-control moonlight
:unity7 moonlight
:wayland moonlight
:x11 moonlight
I'm able to reproduce the issue if x11 and unity7 are disconnected... which is unexpected as these interfaces should be auto-connected on install.
Let's look for any relevant apparmor confinement logs. Please, run the following command in a different terminal, and then run moonlight as usual:
$ sudo journalctl --output=short --follow --all | sudo snappy-debug.security scanlog moonlight
Finally, please try the snap in devmode to rule out any confinement issues:
$ sudo snap remove moonlight
$ sudo snap install moonlight --devmode
$ moonlight
Thanks!

Hey,
thanks for fast reply.
Well ... it's weird:
- I switched to Linux Mint 19.10. (due to some other issues with Lubuntu 18.10 itself)
- after first try with moonlight: same error (even after reboot)
- I installed some stuff like google chrome and Kodi as a media center
- ... then I wanted to start with your suggested commands - and huh? moonlight is running now.
So, for me this issue is solved ;)
Thank you anyway!

Hello. Sorry for late reply. Yes, i tested VLC snap and it worked.

@excelsi0r can you check the x11 and unity7 interfaces are connected, and look for any relevant confinement errors, as described in my comment above, please? Thanks!

@pajew I'd appreciate if you check for relevant confinement errors, as described in my comment above, please? Thanks!

After installing:
sudo snap install snappy-debug
and running:
sudo journalctl --output=short --follow --all | sudo snappy-debug.security scanlog moonlight
I lunched Moonlight from start menu and it worked :)
I stopped debugging and lunched Moonlight again and it worked.
After:
pawel@DeskLinux-P:~$ sudo snap remove snappy-debug
snappy-debug removed
I lunched Moonlight and it works. Strange. I tried to lunch Moonlight just before snappy-debug installation without success.

The problem origins from snap permissions.
When you install sudo snap install snappy-debug it results in reconfiguration of access permissions for snaps. And after that everything works.

@ajvengo care to elaborate, please? How would the installation of a snap affect the permissions of a different snap? Thanks!

I will try to find out how. Currently don't know. Not a pro in snap. Need to read documentation.

I believe this snapd bug is the culprit. Basically, if you only install core18-based snaps, such as moonlight, the core snap is not auto-installed and some basic interfaces are unavailable, including x11.
For the time being, please install the core snap manually alongside moonlight.

snapd 2.39.2 is available in bionic-updates now, so this can be closed now.

Indeed, the snap's interfaces are now auto-connected on install. Tested on a clean ubuntu 18.04. Thanks for the update!
