Wrong Python version - problem with esptool

[speendo]

Thanks for this flatpak.
I installed it on my Debian Testing machine but cannot compile sketches for ESP32 boards. This is what I get:

Traceback (most recent call last):
File "/home/marcel/.arduino15/packages/esp32/tools/esptool_py/2.6.1/esptool.py", line 37, in
import serial
ModuleNotFoundError: No module named 'serial'
exit status 1

As far as I could dig into this issue, I think it is caused by the dependency on the flathub shared libraries. The shared modules seem to provide only Python 2.7.18.

As Python 2 is dying, Debian Testing does not provide /usr/bin/python at the moment. A sustainable solution would probably be a switch to Python 3 which is however not provided by flathub shared modules.

I hope a maintainer can soon find a solution.

The flatpak uses python3, python2 is not even bundled (but could if needed). I will add the serial python3 module later today.

Note that the only shared-module that it is installed is libusb.

I see. Thanks for your help and sorry for not looking closer at this

Don't worry, thanks for reporting.

@speendo could you please try #24 once it finishes compiling (it has not started yet for some reason)? I will trigger a rebuild later.

Thank you Maximiliano!

Now I get

Traceback (most recent call last):
File "/home/marcel/.arduino15/packages/esp32/tools/esptool_py/2.6.1/esptool.py", line 45, in
raise ImportError("""
ImportError:
esptool.py depends on pyserial, but there is a conflict with a currently installed package named 'serial'.

You may be able to work around this by 'pip uninstall serial; pip install pyserial' but this may break other installed Python software that depends on 'serial'.

There is no good fix for this right now, apart from configuring virtualenvs. See espressif/esptool#269 (comment) for discussion of the underlying issue(s).
exit status 1

Is it possible that you should add pyserial instead of serial?

[A6GibKm]

Oops, done, this time the bot started building automatically.

[speendo]

yes! It works for me now. Thank you!

My observation is that

1. esptool.py works on Ubuntu Bionic
2. esptool.py fails on Ubuntu Focal, where pyserial is no longer available for Python2
3. one can run python3 esptool.py on Ubuntu Focal (when pyserial is installed for Python3); maybe this is the solution to the upload troubles

even if I specific the python on top of the file, it still not working

#!/usr/local/bin/python
