I don't know python, but I am guessing that it would be easy enough to fix

this problem for someone who does know python.

Package name: software-properties-common

Package version 0.99.30-4.1~deb12

File name: add-apt-repository

Error:

Traceback (most recent call last):
  File "/usr/bin/add-apt-repository", line 361, in <module>
    addaptrepo = AddAptRepository()
                 ^^^^^^^^^^^^^^^^^^
  File "/usr/bin/add-apt-repository", line 39, in __init__
    self.distro.get_sources(self.sourceslist)

    raise NoDistroTemplateException(

Thanks,
