New RUTX11- can't install Nano anymore?

Hey, I have a script I’ve been using, on all new RUTX11 modems, which updates the opkg repositories, and installs Nano as a text editor. Based on info found here-

My latest one doesn’t like the script. Keeps coming back with “Unknown package ‘nano’”

This one is FW version 7.22, all my older ones are 7.20 at the latest.

Is there something else I could try?
