Hello,
I tried to debug with a friend what is happening...
It seems the function "bcr.decode" is not working properly when running on terminal on a graphical environment.
But we don't know how to make it work.
We added a print behind bc definition:
print("**",bcr.decode(ff))
bc = bcr.decode(ff, try_harder=args.try_harder)this is working through ssh:
zxing /home/user/alb0008.tiff
** BarCode(raw='1234|000', parsed='1234|000', path='/home/user/alb0008.tiff', format='PDF_417', type='TEXT', points=[(2425.0, 814.0), (2426.0, 925.0), (2914.0, 816.0), (2914.0, 926.0), (2494.0, 814.0), (2495.0, 925.0), (2840.0, 816.0), (2841.0, 926.0)])
/home/user/alb0008.tiff
======================
Decoded TEXT barcode in PDF_417 format.
Raw text: '1234|000'
Parsed text: '1234|000'and this output is through graphical:
zxing /home/user/alb0008.tiff

I have different output running the command from ssh and from graphical....
🤨
Are you sure you are running the same version of ZXing both via ssh and via the local "graphical" terminal? I'm skeptical.
I'm guessing that in at least one place, you're running a version of python-zxing that does not include the bugfix in 980a045.

Hello, thank you for taking your time to look over my question.
After lot of changes I'm going to uninstall everything and start from zero:
#pip3.11 uninstall zxing
Found existing installation: zxing 1.0
Uninstalling zxing-1.0:
Would remove:
/usr/local/bin/zxing
/usr/local/lib/python3.11/site-packages/zxing-1.0.dist-info/*
/usr/local/lib/python3.11/site-packages/zxing/*
Proceed (Y/n)? y
Successfully uninstalled zxing-1.0
# locate zxing
/usr/local/bin/zxing
/usr/local/lib/python3.11/site-packages/zxing
/usr/local/lib/python3.11/site-packages/zxing-1.0.dist-info
# updatedb
# locate zxing
# pip3.11 cache purge
Files removed: 3
Now I'm going to install it again with python 3.11. When issue was open, zxing was installed with python3.9
# pip3.11 install zxing --proxy http://192.168.x.x:8080

Successfully installed zxing-1.0now let's see line 52 in main.py:

51 try:
52 bc = bcr.decode(ff, try_harder=args.try_harder)
53 except BarCodeReaderException as e:
54 p.error(e.message + ((': ' + e.filename) if e.filename else '') + (('\n\tCaused by: ' + repr(e.__cause__) if e.__cause__ else '')))there is no "bc=none", so I added it in line 52 and running zxing command through ssh and graphical terminal
so:

51 bc = None

ERROR: Failed to decode barcode (using Java ZXing library v3.5.1).I think is failing to decode barcode because "bcr.decode" function is not working in graphical... ( test made in answer 2 )

Ok, I think I have found the problem:
Trying messing with python in graphical terminal:

The above exception was the direct cause of the following exception:
