Use groupadd command. Have a look at https://wiki.archlinux.org/index.php/Users_and_groups

Rather than trying to use the commands that work on another system, you'd be far better learning about their end goal so you can acheive the same goal on your system which may use entirely different group names.

The intent is to have read/write access to ttyACM0. So you want to assign your user to a group that has r/w access to that device. I don't have such a device handy, but last time I did, it did have a group already assigned. Use that instead of "dialout". Plug in, connect, or whatever the device in question, then do `stat /dev/ttyACM0` and post the output here.

So you need to add your user to the uucp group instead.

Thank you it looks like the problem is somewhere else - python-Xlib is conflicting with python3.6
