i tested tool with A13 firmwares like OPLUS(oneplus/oppo/realme) and moto a12/a13
when doing resigning on LINUX( ubuntu , resginer works but fails to resgin for some reason and it detect all apps/jars,

meanwhile on WSL,
OS: Ubuntu 20.04.5 LTS on Windows 10 x86_64
Kernel: 5.15.79.1-microsoft-standard-WSL2
Resigner unable to detect even all apps/jars.

Got this while using the resign python script :

Traceback (most recent call last):
File "resign.py", line 33, in
xmldoc = minidom.parse(mac_permissions)
File "/usr/lib/python3.8/xml/dom/minidom.py", line 1959, in parse
return expatbuilder.parse(file)
File "/usr/lib/python3.8/xml/dom/expatbuilder.py", line 913, in parse
result = builder.parseFile(file)
File "/usr/lib/python3.8/xml/dom/expatbuilder.py", line 204, in parseFile
buffer = file.read(16*1024)
AttributeError: 'NoneType' object has no attribute 'read'

Where is the problem ?

Traceback (most recent call last):
  File "/home/penn/ROM_resigner/resign.py", line 33, in <module>
    xmldoc = minidom.parse(mac_permissions)
  File "/usr/lib64/python3.10/xml/dom/minidom.py", line 1988, in parse

Because /etc/ should be /system/etc/
