Tried to: Flash Interface firmware with USB cable

Problem:

console shows

statusCode: 200

Workaround:

sudo chown $USER '/opt/OpenBuildsCONTROL/resources/app.asar.unpacked/esptool.py'

Pyserial is not installed for /home/dheera/miniconda3/bin/python3. Check the README for installation instructions.

Traceback (most recent call last):
  File "/opt/OpenBuildsCONTROL/resources/app.asar.unpacked/esptool.py", line 38, in <module>
    import serial
ModuleNotFoundError: No module named 'serial'

Solution: $pip3 install pyserial

Pull requests accepted if you find a way to fix permissions from within the install, as well as dependencies like users python

You could maybe look into a script (universal for all DEB targets) https://github.com/electron-userland/electron-builder/issues/2065 to run from afterInstall (sudo escalation, do chmod, check if python/pyserial is installed if not install)
