usermod: group 'gpio' does not exist

[gounthar]

Hi,

I just installed OPi.GPIO on my OrangePi Zero running Armbian buster with Linux 5.4.31-sunxi.
I followed the documentation but got the following error:

sudo pip3 install --upgrade OPi.GPIO

Installing collected packages: OPi.GPIO
Successfully installed OPi.GPIO-0.4.0
sudo usermod -aG gpio poddingue
usermod: group 'gpio' does not exist

Do I have to create the group gpio by myself, or should the pip3 install do it for me?
Thanks.

You should create it yourself. Pip3 won't do it for you. I am surprised the group does not already exist in the os though.

I will report to the distro maintainers, thanks.
