I think Omada Controller Linux does not support Debain system now. But I found a post for how to install Omada Controller 3.0.2 in Debain, hope it may help you....

Hi jobnn, The TP-Link said the minimum RAM requirement of Omada Controller is about 2G, I think the RAM of Raspberry Pi is just 1G, do you think if it may affect the performance of Controller?

I have received an OC200 today and am suffering the same 'starting up' splash screen. I have waited 15 minutes for it to clear, but no progress. Then it seems to lose it's IP address and Chrome...

Great! Thank you for sharing!

I think TP-Link does not have Docker Container example for Omada Controller, where did you see the early version container?
