What happened?

Tried running ./install-wifi.sh on Arch Linux with esptool.py v3.0 installed in virtualenv

Got the following output (I added set -x to the script)

++ Bootloader='0x1000 wifi/bootloader.bin'
++ Bootapp='0xe000 common/boot_app0.bin'
++ Firmware='0x10000 wifi/firmware.bin'
++ Partitions='0x8000 wifi/partitions.bin'

If I comment out the check_security function it works, and I have successfully flashed and configured wifi (so it did not brick my esp32).

Looks to be a bug in esptool.py or something about my particular board.

I tried different cables and usb ports, no change. I tried erasing the flash with esptool, and that didn't change anything either. Tried changing the baud rate from the default and that didn't help either.
