while upgrading from 184.108.40.206 to 16.2.1 450 and 450i APs using cnut there is a pop up warning says something like:
"Warning: SMs running firmware 15.1.5 or lower do not register to an AP running firmware 16.1 or later. Do you want to proceed with the upgrade anyway?"
I have to accept clicking "Yes".
This happen when my APs are *already* with a firmware 220.127.116.11, so it's unuseful.
The problem is that I have some scripts upgrading my devices from cli (./updatedevice.sh) returning the error:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
Can we aboid this warnig? Scripts don't have to have a human interaction.
At least when APs are already with a firmware > 16.1?
