x11docker ERROR: Could not find user

[leoyala]

Hello,

I am trying to run some of the basic commands from x11docker: x11docker --update but I run into the following error that I do not understand, perhaps x11docker requires different privileges? I am using Ubuntu 22.04, I did the installation as stated in the README, and also pulled the x11docker/xserver image. I did check that the user indeed exists by running id -u <user_name>

DEBUGNOTE[17:21:05,070]: Detected cgroup v2
DEBUGNOTE[17:21:05,260]: check_host(): ps can watch root processes: yes

Have the same problem with MSYS2 setup, there is no /etc/passwd at all.

$ x11docker --verbose prosys-opc-ua-simulation-server
stat: cannot read file system information for '/sys/fs/cgroup': No such file or directory

i have the same problem. The authentication method changed to ldap in my machine, so my is not part of passwd file

Do you have any suggestions for this?

Unfortunately, I do not have an answer for this yet. I stopped using x11docker because of it.

Does "getent passwd your_user_name" (using your actual username) show anything in the terminal, or give an error? (On msys, you might need to install the getent package first.) You can probably avoid the "--update" by downloading the latest copy from GitHub manually, and you can skip installing it by running it from the directory where you cloned the repo. However, if you're seeing this issue, the other basic commands might show errors too.

Doing getent does display something in the terminal, no errors.
