Not working when I build myself. [Dependency issues | snap | Ubuntu server]

[iamneo2416]

I use ubuntu20.04LTS server (console based system) as a host and download x11docker/mate image. When I run it by command "x11docker --desktop x11docker/mate" in console, I got following error. I install all suggested package from following error, and re-run many times without luck. Did my process go wrong anywhere or did I miss something? Please help with this.

X11 connection rejected because of wrong authentication.

Do you have a monitor connected to the server?
If yes, x11docker should start with Weston and Xwayland automatically.
Please try:

x11docker --desktop --weston-xwayland x11docker/mate

A debug output would help me to analyze the problem.
Please show me the output of:

x11docker --debug --desktop x11docker/mate

[iamneo2416]

by the way my environment is as below. my target os is virtualbox os image.

OS: windows10
SW:

1. window version Virtualbox (6.1.2 r135662 (Qt5.6.2)) ==> install ubuntu20.04LTS server image. inside image, install docker engine and pull x11docker/mate
2. use MobaXterm which can generate display XWindow in windows10 environment automatically.
3. install all error suggested software xephyr, xpra, nxagent, weston, xwayland, and xdotool on ubuntu20.04LTS server

You can try a clean ubuntu20.04LTS one, you will find it not working as described. If I use win10 virtualbox to install ubuntu20.04 desktop version and run it. AND, use mobaxterm to login and run xterm or xclock, it will shows up xterm, xclock XWindow successfully inside win10 environment !!

[mviereck]

Thank you for the detailed information.
The debug output shows that x11docker misses xinit. Please install xinit and try again.
x11docker should have shown in the regular output that it misses xinit, but it did not. I'll check that.

[iamneo2416]

x11docker ERROR: dockerrc(): Did not receive PID of PID1 in container.
Maybe the container immediately stopped for unknown reasons.
Just in case, check if host and image architecture are compatible:

It shows up an empty XWindow , error occur and stop! XWindow closed.

[mviereck]

I see two possible reasons for the issue:

• Issues with mobaxterm. x11docker is not tested with mobaxterm. Please try to run without it.
• A complain about XDG_RUNTIME_DIR:

XDG_RUNTIME_DIR "/tmp" is owned by uid 0, not our uid 1000

Please try x11docker --weston-xwayland x11docker/mate mate-terminal to run a single application only that should not depend on XDG_RUNTIME_DIR.

[iamneo2416]

You should try yourself !! Not working ....

Use Win10
(1) download and install Virtualbox and select ubuntu server 64-bit
(2) download and install ubuntu20.04LTS server
(3) install those package you suggested on your github and run.

You will see a lot of problem you never see and documented before. All you document on your github is not working even I follow exactly steps you provided.

(1) close mobaxterm (do not use it)
(2) login to ubuntu directly via virtualbox vm login console >>>

(3) run command from console directly >>

(4) see vm console turn into xwindow mode, but seems to has problems still. Failed again !

[mviereck]

I've tried Ubuntu server 18.04 in VirtualBox on Linux andI found there was a python issue.
It does not provide a python command but python3 only. x11docker also had a check failure for python. This is fixed now.
Please update with x11docker --update-master and try again.

(Also there will be a message if xinit is missing.)

[mviereck]

@iamneo2416 I've transferred the ticket to x11docker.

[eine]

You should try yourself !! Not working ....

@iamneo2416 please be respectful. You are demanding that a single person spends his time and effort for free on solving a problem for you to use a non open-source tool maintained and sold by a company for profit, which is to be tested on a non-free operating system (which @mviereck does not use). I beg to strongly disagree with you. @mviereck should not try anything himself. He should not spend a single minute on supporting mobaxterm. He can do it if he feels like and he has fun while doing so. Conversely, you should try any of the following:

• Fix it yourself.
• Demand mobaxterm maintainers/developers that spend time on looking into compatibility issues (as long as you are paying for the product).
• Hire someone else for fixing the problem for you.
• Be very patient and as friendly and helpful as possible with @mviereck, including trying yourself whatever you might have expected him to do.

[iamneo2416]

@mviereck I am sorry. It is still not working ....

(1) use x11docker --update-master

(2) use x11docker --weston-xwayland x11docker/mate mate-terminal

(3) core dump as follow
x11docker.log

I am sorry. I need to give up this, since I just want to tried out what he build, but nothing work for me. sorry again ! x11docker has some problem with virtualbox, maybe I don't know how to use it. sorry again. I am not a tech guy, and don't know how to fix it.

I will go for other solution. thanks !

[iamneo2416]

I am also doing this try out for fun, since you are not interested in knowing detail of how other met situation and problem. This is also not my responsibility to report bug to you. I also spend a lot of my own time to write report. I think you should consider all cases only if you are a developer. If not, then just skip what I am reporting here. I don't mean to fight with you. That depends on you for perfection or not. thanks for your time anyway.

@mviereck : I have installed xinit too from last tried, still failed !

The other solution seems 100% worked for me on all cases no matter if I use direct console to run or mobaxterm. Again, I am also tried out for fun.

[mviereck]

Sorry for my late response, curently i am a bit rare online and at x11docker.

@iamneo2416 thank you for the bug report! Sorry for the disturbances.
Basically you and @eine are both right.
In fact x11docker depends on both my work and on feedback by the users. It is used in a lot of very different environments an I cannot set them up all myself to reproduce issues. Mostly I can fix issues by asking questions and getting feedback.
Sometimes I get bug reports for very special setups but get no response to my questions. I don't fix those issues anymore. The linux world is just too big to reproduce everything. So fixing a bug depends on both the users and the developers.

For this bug I've set up VirtualBox and reactivated and old Ubuntu server 18.04 VM. Currently I get issues in it, too.

Ubuntu server installs applications with snap but tries to hide this. But docker in snap does not work well and has serious limitations. Docker in snap means a container tool within another container tool. This is a bad setup done by Ubuntu.

For now a possible workaround is to use options --cap-default --xoverip to circumvent snap limitations.
Example:

x11docker --desktop --cap-default --xoverip x11docker/fvwm

[mviereck]

I have checked this again.
In my Ubuntu server VM Docker in snap is detected and supported if only this is installed.

If Docker is installed in snap and also with apt, there can be interferences and x11docker fails.
x11docker prints a message if it detects /snap/docker but also /usr/bin/docker.

New option --snap allows to manually enable docker-in-snap fallback mode.
