PnCConf vs. Raspberry Pi 5

Hello,

I've got a home built router running a Raspberry Pi 4 with a Mesa 7196s via Ethernet. Running AXIS. Works fine.
Interested in trying the Rpi5 - loaded the image off the download page and the board can communicate with the Mesa board, but PnCConf keeps giving errors when I try to go past the first axis page - a long dump mentioning a problem with the locale.
Any suggestions? This is an 8GB RPi5 I just got from Digi-Key.
 

run the menu-config (menu_config) and set the locale.
