Status changed to 'Confirmed' because the bug affects multiple users.

[elguavas (elguavas.)]

as pointed out in bug #1923553 , this bug affects all the various software-properties gui's (including software-properties-qt, software-properties-kde), not just software-properties-gtk.

it is also mentioned in the other bug report that the issue seems to be that the underlying python code being called is using the long deprecated and now removed "getiterator" method in ElementTree to generate the list of "other" download sources.

[Launchpad Janitor (janitor)]

This bug was fixed in the package software-properties - 0.99.10

---------------
software-properties (0.99.10) hirsute; urgency=medium

  * softwareproperties/CountryInformation.py:
    - Remove use of getiterator which is deprecated in python3.9
      (lp: #1909918)
