So I am following instructions for how to install Kiauh on Arbmian. I am using a terminal on my PC through PuTTY. I have cloned the Kiauh files to my device successfully, I have verified they are there, but whenever I try to run the shell using sh ./kiauh/kiauh.sh I get the response 'unknown': I need something more specific. This is the least useful error message I have ever seen. I can't find anyone having had this issue and I am dead in the water. Any insight would be greatly appreciated!
