RPi Zero workaround not working

[sensboston]

I'm trying to run TalkiePi on RPi Zero (Mumble server is also running on this RPi); everything from installation manual went smooth except workaround for RPi Zero.

I'm getting:

I'm on latest RaspberryPi OS (Raspbian), installed yesterday. Already did apt-get update & apt-get upgrade
Any suggestions? I'm not a Linux expert, so could you please ask me for additional info with some commands examples? Thanks!

It's duplicate of #16
Probably, solution should be added to project's wiki.
