[Bug 1180034] Re: backend_helper.py wants update-manager

[Brian Murray]

backend_helper.py is only called with show_updates by the tray applet
which should be going away in Saucy.

>From src/update.c:

// command, description, desktopfile, needs_pkexec
const char* actions[][4] = {
   { "/usr/lib/update-notifier/backend_helper.py show_updates",
     N_("Show updates"), 
     "/usr/share/applications/update-manager.desktop", 
     GINT_TO_POINTER(FALSE) },

Title:
  backend_helper.py wants update-manager

Status in “update-notifier” package in Ubuntu:
  Triaged

Bug description:
  backend_helper.py uses update-manager to show updates:

  # show updates
  def show_updates():
      """ show updates using update-manager """
      cmd = ["update-manager", "--no-update"]
      res = subprocess.call(cmd)
      return (res == 0)

  However, backend_helper.py is shipped as a part of update-notifier-
  common and update-notifier-common does not depend on update-manager.

  Package: update-notifier-common
  Priority: optional
