Sometime back I was able to install the Omada Controller on a Raspberry Pi. Its working great and no issues. My controller is on version 5.13.22. Every time I log in I am prompted to update to version 5.15.8. It then prompts me to download the update file but I cant figure out a way to install on the Pi device. Can anyone point me in the right direction as to how? Also I enabled SSH on the controller but my credentials are not working. Where can I add other user accounts within the controller?
