[Bug 828850] Re: software-properties-gtk crashed with DBusException in call_blocking(): com.ubuntu.SoftwareProperties.PermissionDeniedByPolicy: com.ubuntu.softwareproperties.applychanges

[Edward Donovan]

The whole privilege-checking section of the code looks like it was
copied from the 'jockey' app.  It starts at line 306, the comment "#
helper from jockey":

  http://bazaar.launchpad.net/~ubuntu-core-dev/software-
properties/main/view/head:/softwareproperties/dbus/SoftwarePropertiesDBus.py#L306

(AFAICT, that code predates the bazaar history, which shows the file
arriving in one piece, including the main part of this code.)

Later, I'll try to look at jockey and see if it now handles this better.
Thanks.

Title:
  software-properties-gtk crashed with DBusException in call_blocking():
  com.ubuntu.SoftwareProperties.PermissionDeniedByPolicy:
  com.ubuntu.softwareproperties.applychanges

Status in “software-properties” package in Ubuntu:
  Triaged

Bug description:
  This is reproducible by launching software-properties-gtk as any user
  that is not an admin, or from any session where the user can't be
  verified to be an admin via policykit - including when the user hits
  'cancel' in the authentication dialog. We should suppress these
  exceptions so they don't show up as crashes on the desktop.
