Bug Description

Pro primo: Software & Updates cannot start, when I click to the button, it does not show anything. When I try to launch it from the terminal with software-properties-gtk, I get a beautiful error message:
Traceback (most recent call last):
  File "/usr/bin/software-properties-gtk", line 100, in <module>
    app = SoftwarePropertiesGtk(datadir=options.data_dir, options=options, file=file)
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    source_bkp = SourceEntry(line=source.line,file=source.file)

    raise ValueError("Classic SourceEntry cannot be written to .sources file")
ValueError: Classic SourceEntry cannot be written to .sources file

I can program in Python at a medium level, but it is too much for me. Application version: 0.99.42

Pro secundo: Software Updater crashes without any error message, when I empty the checkbox of an arbitrary package. Application version: 1:24.04.4

Excluded that and a few such errors, congratulations for Noble Numbat, it is really nice!

sourceslist.py Edit (36.7 KiB, text/x-python)

I was able to fix the first-mentioned problem by changing /usr/lib/python3/dist-packages/aptsources/sourceslist.py (I attached the fixed version as a patch to this message). It disabled .sources extension to the handled files, causing that problem.
