Snap: build against 20.04

[dasgarner]

We still build against 18.04 when snapping, but we're using 20.04 in our dev container. Investigate whether we can no build against 20.04 and see if that enables us to reduce some of our compilation requirements.

The player won't start: ERROR: not connected to the gnome-3-28-1804 content interface

What if you remove xibo-player completely and then install from edge? Seems like during update it didn't reconnect slots correctly.

UPD: Hmm, from stable to edge channel it refreshed without errors on my laptop P.S. Ubuntu 18.04

[Stivius]

OK, for some reason snap image (.snap file) is built with gnome-3-38 extension but when pushed to edge and then installed from edge it uses gnome-3-28 connection which is odd. Could you manage connections for this snap on the snapcraft.io page?

I did try a complete reinstall, but same results.

I reverted edge to the previous working version as there are 107 people using it. edge does mean that it might break, so I have republished r240.

I then tried the refresh on another machine and this time it worked.

There aren't any options for that in the store UI.

Yes this looks to be exactly right, if it list connections there are empty slots. I am not at that machine now, but I can get the output of snap connections xibo-player and post here.

On the working player, none of the web based content works, the browser renders with the following error inside it:

GDBus.Error:org.freedeakstop.portal.Error.NotAllowed This call is not available in the sandbox

That happened due to snap environment probably... On my machine, everything works as expected, including web rendering. It's pretty weird how sandboxed environment produces very different behaviour every time

Here is the output for snap connections xibo-player on the machine which gives this message:

I also tried running, to try and link the same interface/plug as on the working laptop.

[dasgarner]

I did a complete reinstall again, and this time the same PC to generate the above output, worked fine on edge and the web browser content works too.

I can't explain why a reinstall did not work the first time around, but has worked this time.

Edit: web content works too!

[dasgarner]

I've tried a complete reinstall under Wayland, and the tricks you linked above, and I can't get past:

GDBus.Error:org.freedeakstop.portal.Error.NotAllowed
This call is not available in the sandbox

[BOFHELL]

Have fixed it by add the network-status plug...

1. snap download xibo-player --channel=edge
2. unsqahsfs xibo-player_240.snap
3. vim squashfs-root/meta/snap.yaml
   search section for xibo-player and add - network-status (line 51)
4. snap pack squashfs-root
5. snap install xibo-player_1.8_R7_amd64.snap --dangerous

done :)
