I try to install OctoPrint of an Odroid C1+ from this manual https://community.octoprint.org/t/setting-up-octoprint-on-a-raspberry-pi-running-raspbian/2337.
First I update the system, then I create a user - add the user to the sudo group. Then I follow the instructions from the link above. When I set this command
I get the followin error: -sh: 6: source: not found
Please can someone help me to solve the problem?
