The core error message is exec: "docker-init": executable file not found in $PATH.. Maybe you have an outdated version of docker? Please show me the output of docker --version and of docker run --help | grep init.

It seems to me you have an old docker version without option --init. I have uploaded an update of x11docker-gui that does not use this and should work for you.

For your images you will probably have to set option --no-init to avoid this error. I recommend you to update docker.

[mviereck]

I've added a check in version 3.9.3 whether docker provides option --init and disables it otherwise. It will show a warning, but should work for you now without doing anything special. Thanks for reporting! Feel free to reopen if the issue persists.

$ docker run --help | grep init
      --health-start-period duration   Start period for the container to initialize before starting health-retries countdown (ms|s|m|h) (default 0s)
      --init                           Run an init inside the container that forwards signals and reaps processes

$ docker --version
Docker version 17.09.1-ce, build f4ffd2511ce9

It doesn't appear older version of docker is the problem.

[mviereck]

Strange; your docker version supports option --init. From the error message above I thought you have a quite older version.

It doesn't appear older version of docker is the problem.

I don't think so now.
Can you please show me the full verbose output with option -v?

And can you try to run a docker image with option --no-init, for example

 x11docker -v --no-init x11docker/lxde pcmanfm

and show me the output if it fails?

I have the new version now btw.
If for instance, I run the x11docker-gui it just closes without no indication. In the cmd line it even returns just a 0 code.

[mviereck]

Can you please show me the output of

x11docker --verbose --no-init x11docker/lxde pcmanfm

?

The error message from your lightworks image could also mean that it has no CMD specified or the command is just not in PATH. Failing x11docker-gui could be a different issue. The command above should not fail in any case, I could analyze the output better.

[Greenscreener]

working on it, but it is downloading a lot of things (I don't have the lxde image)

This is the Dockerfile of the lightworks image:

FROM ubuntu:latest
RUN apt-get update -y && apt-get upgrade -y
RUN apt-get install wget -y
RUN wget "https://www.lwks.com/index.php?option=com_docman&task=doc_download&gid=194" -O lightworks.deb
RUN dpkg -i lightworks.deb || true 
RUN apt-get install -f -y
RUN groupadd -r lightworks && useradd -r -g lightworks -G audio,video lightworks && mkdir -p /home/lightworks && chown -R lightworks:lightworks /home/lightworks
USER lightworks
ENTRYPOINT ["lightworks"]

[mviereck]

ok, I am building the lightworks image, will take a while, too. :-)

Did pcmanfm from lxde image run well? The logfile looks sane and successfull.
