daemon fails to start on ubuntu-core #10

Closed osccto closed 11 months ago

osccto commented 1 year ago

I installed ubuntu-core on an intel system (amd64).

I then installed ubuntu-frame and ubuntu-frame-vnc. The ubuntu-frame was running fine (and displayed on the screen), but the ubuntu-frame-vnc not:

$ snap logs ubuntu-frame-vnc.daemon

That is an odd failure mode (one I've not seen before).

Could you list the contents of /run/user/0?

osccto commented 1 year ago

In /run/user/0, I found:

$ sudo ls -lrt /run/user/0
total 0
-rw-r----- 1 root root   0 May 12 16:42 wayland-0.lock
drwx------ 2 root root  80 May 17 09:38 snap.ubuntu-frame-vnc
srwxr-xr-x 1 root root   0 May 17 09:38 wayland-0
drwx------ 4 root root 100 May 17 10:51 snap.our-electron
drwx------ 2 root root  80 May 22 08:08 snap.ubuntu-frame-osk

That looks normal. So I need to ask some more questions...

I assume your snap (our-electron) and ubuntu-frame-osk are connecting OK?

Could you also list the content of /run/user/0/snap.ubuntu-frame-vnc?

Thanks

Note for anyone following up on this:

2023-05-17T09:38:10Z ubuntu-frame-vnc.daemon[22733]: ERROR: ../src/src/main.c: 384: WAYLAND_DISPLAY is not set in the environment 2023-05-17T09:38:10Z ubuntu-frame-vnc.daemon[22733]: ERROR: ../src/src/main.c: 1391: Failed to initialise wayland

These logs are output by wayvnc after and because wl_display_connect(NULL) fails. There is no indication logged why this failed (it isn't caused by WAYLAND_DISPLAY not being set, that's just logged in case it is useful).
