I recently came to note that a new version of firmware is available.  Via the console, when you click the "check" button it prompts that a new revision is available.  It then provides a "download" option, but this only downloads locally.

I SSH to the controller and 'wget https://static.tp-link.com/upload/software/2024/202402/20240227/Omada_SDN_Controller_v5.13.30.8_linux_x64.tar.gz' to downlaod, which all works fine.  The completed the "tar -xf <filename>" to extract, but when running the "install.sh" script, it advises 

Installation start ...
An incompatible controller version has been detected. 

What steps are required?   Any reason the appliance can't download internallly and upgrade, rather than having to do it via the CLI?
