I've create an sd card with Etcher and i put the original bios (Antminer-S9-all-201812051512-autofreq-user-Update2UBI-NF.tar.gz) into the sd card, switch jumper for start from sd and run the s9.
I've download the ssh version and type this command from terminal.
Where's the error?
[...]
Did you run (linux):
cd braiins-os_am1-s9_ssh_VERSION
virtualenv --python=/usr/bin/python3 .env
source .env/bin/activate
pip install -r ./requirements.txt
That is what fixed that error for me and was the recommendation from Braiins support. Seems you need to be using virtualenv and install everything in requirements.txt so that you have a proper python3 environment.
