software-properties-gtk: AttributeError: 'UbuntuDistroInfo' object has no attribute 'get_all'
When running the software-properties-gtk, I get this error:
AttributeError: 'UbuntuDistroInfo' object has no attribute 'get_all'

Tried a bunch of things, from reinstalling it, trying to reinstall or install different dependencies...
  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)
