Deconz container doesn't start after update

deCONZ General Support
1

Hi all,

I am running deconz on a Raspberry 3B in a docker container with docker-compose and everything is working fine. Today I wanted to update from the old marthoc/deconz to the latest deconzcommunity/deconz image. When I follow the instructions and change the entry point, the container still does not start. At startup I get the following error message displayed in the log:

qt.qpa.xcb: could not connect to display :0
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

Does anyone know the problem or can help me?
Best regards,
Jörg

Can you please give the full docker log as well as the docker-compose config with DECONZ_START_VERBOSE=1?

Sure :slight_smile:

Can you get that log?

5

To be honest, I don’t know how. The log is only in the container available and I can’t connect to it because the container crashes and doesn’t start properly.

6

Can I ask why you need VNC? You can disable VNC by using DECONZ_VNC_MODE=0.

To bash into your container: docker exec -it container_name /bin/bash

7

I use VNC to see the topology of the devices: who is connecting to whom.

I know how to connect into a container. But that only works if the container can be started. In my case it does not come up at all including VNC.

When I start the container without VNC, it comes up. Meaning my problem is with the startup from the VNC server? Can I fix this?

8

Perhaps starting the container without VNC would help getting the log file and see what is causing it, to try to solve the issue.

9

Unfortunately, I can’t manage to get the log file. When I run the container into error and then restart it, it deletes the log from the previous instance automatically.
I have also tried to persist the log to a volume:

/var/dresden-elektronik/deCONZ/home:/opt/deCONZ/vnc

Then a log file is written there, but it is always empty. :roll_eyes:

10 
 - "DEBUG_INFO=1"
  - "DEBUG_APS=0"
  - "DEBUG_ZCL=0"
  - "DEBUG_ZDP=0"
  - "DEBUG_OTAU=0"

Need to be set to:

 - "DEBUG_INFO=2"
  - "DEBUG_APS=2"
  - "DEBUG_ERROR=2"
11

Then you are able to get the log, right?

12

You should mount /home/deconz/.vnc/to a persistent volume.

13

I tried that first. But that doesn’t work either because .vnc is just a link to /opt/deCONZ/vnc

14

So you should have the log in /opt/deCONZ/vnc?

15

I would say that doesn’t change much:
