Error Message:

I think the last two "errors" or let's say warnings can be ignored. Depending on the machine that I am using, I also sometimes get these kind of warnings. Did you try to run some of the exercises ? If the exercises run fine, then this warning can be ignored.

However, the error xauth: file /home/linchuan/.Xauthority does not exist might cause problem when using RVIZ or some other UI in the docker environment. Can you try to run RVIZ in the container ? Maybe it is necessary to create the .Xauthority directory in your home directory.

Thank you for your answer. Currently I have problems when running 'rqt' command under the running container and I got the following error:

I think this might caused by some errors when setting up the XLaunch configuration. I followed the steps to set up the xlaunch configuration file, but where I should I save this configuration file so that it can be used in WSL?

[TillBeemelmanns]

So do not necessarily need to save your configuration for Xlaunch to a file. It is sufficient to click on finish after "Configuration Complete"

Regarding my response above: Did you check if the file /home/linchuan/.Xauthority does exists in your WSL environment ? If this file is missing, it could cause problems like you currently have. Further more you can try to run

xhost +

rqt

[TomyangSydney]

Thank you for your response. I tried to create the file /home/linchuan/.Xauthority following this guide: https://superuser.com/questions/806637/xauth-not-creating-xauthority-file. Although the error xauth: file /home/linchuan/.Xauthority does not exist disappear, I still get the error mentioned in the last post after executing "rqt". Here is the result:

Another question is about the VcXsrv, after I run "xhost +", I get the error:
Do i need to install any other libraries in WSL apart from only choosing the first option in the window?

Thank you in advance for your help.

Thank you for your answer! I tried the first one to update wsl and it works this time! Very appreciated!
