Error during package upgrade: Failed to byte-compile extendedsourceslist.py

[zapyon]

During a regular update of updatable packages I got this message for the software-properties package in the shell:

----8<----
python3-software-properties (0.99.13.1) wird eingerichtet ...
Failed to byte-compile /usr/lib/python3/dist-packages/softwareproperties/extendedsourceslist.py: File "/usr/lib/python3/dist-packages/softwareproperties/extendedsourceslist.py", line 436
    def __init__(self, sourceslist=None, /, files=None):
                                         ^
SyntaxError: invalid syntax (expected ')')
---->8----

After the installation process is finished the package is marked as installed, not as corrupted in aptitude.

Regards

Andreas
