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.

We are not highly motivated to fix it given that the new Web Installer https://installer.fluidnc.com/ is generally more convenient and works better than the install scripts. It is more likely that we will just drop the install scripts entirely. Linux has proven to be difficult to support.

Ok, I will try the web installer. I think it will be useful to have a comment somewhere about this in case anyone else comes across this problem with esptool

http://wiki.fluidnc.com/en/installation . "Somewhere" doesn't guarantee that any individual will see it, especially when there are an arbitrary number of old instructions and videos that someone might come across.
