This is a follow-up to closed issue: #2610
I followed the steps of issue #2360 and had no success. Today I started my machine and removed Thonny, reinstalled it with your file thonny-4.0.1.bash and well, I can connect to the ESP8266. But there is always an error message:
_Traceback (most recent call last):
File "/home/heinz/apps/thonny/lib/python3.10/site-packages/thonny/plugins/esp/esp_back.py", line 5, in
from thonny.plugins.micropython.bare_metal_backend import (
ModuleNotFoundError: No module named 'thonny.plugins.micropython.bare_metal_backend'

Process ended with exit code 1._
Thonny-ModuleNotFoundError-2023-01-15 13-44-21

I looked through all the mentioned paths in the error message, and did not find anything missing. See attached screenshot.
What is going wrong?

Thank you for the report!

Please reproduce this issue and then, without doing anything else, select "Tools => Options => Open Thonny data folder" and post the backend.log you find in this folder.

I have done so. But the file backend.log does not show anything. There was an old file of the same name, dating back to the 12. December 2022 (attached). But I think this has no relevance. I created a new backend.log file but it stayed empty. The frontend.log contains some information (attached). Have I to change Thonny's settings? Mine are as shown in the screenshot (attached). Also the export of the protocol files does not show any results. The zip file is empty.

I'm afraid you have both new and old Thonny versions in your system.

Do you have thonny in ~/.local/lib/python3.10/site-packages ? If yes, then please delete it from there and try again.

Many thanks! Yes, this was the problem. I removed the directory thonny in ~/.local/lib/python3.10/site-packages and the new Thonny-installation works perfektly! I am so happy! And it is a lot faster than under windows!

In the next Thonny version Thonny should not be confused by other installations anymore.

* Misc fixes for esptool GUI, thonny#2707

* Use UDisks to find mounted filesystems on Linux (thonny#2683)

* Use UDisks to find volumes on Linux

This should generally work better on Linux than using the mount command directly.
UDisks is the utility that all major Linux desktop distributions use to handle mounting filesystems in userspace.
UDisks is accessible through a D-Bus API on the system bus.

D-Bus is complex and requires adding a dependency on a Python library for handling asynchronous communication with the bus.
I chose dbus-next since it is actively developed, modern, and doesn't require a glib main loop.
Since Thonny is not a Gtk application, it makes more sense to use native Python async functionality instead.

Inside a Flatpak, it's necessary to use UDisks via the D-Bus API to mount and check mounted filesystems.
The Flatpak sandbox prevents mounting otherwise and does not supply a mount command with the runtime.

More conservative approach implemented in d2a96d0 because of #2851 and #2864.
