Use PackageKit interface to aptdaemon

[Ken VanDine]

aptdaemon in precise now includes support for the PK API, which is the preferred method for determining the state of updates. This should be more reliable than the current approach indicator-session uses and hopefully will resolve a few of the open bugs related to update notification.

Here is a short python example:

from gi.repository import PackageKitGlib as pk

client = pk.Client()
res = client.get_updates(pk.FilterEnum.NONE, None, lambda p, t, d: True, None)
updates = 0
security = 0
for pkg in res.get_package_array():
    updates += 1
    info = pkg.get_info()
    if info == pk.InfoEnum.SECURITY:
        security =+ 1
print "There are %s updates available totally" % updates
if security:
    print "There are %s important security updates!" % security

You should query for the updates some minutes after the session is started and after the org.freedesktop.PackageKit.UpdatesChanged() signal has been emitted. There is no need anymore to query for updates after each completed transaction. The signal gets emitted by packagekit/aptdaemon after each transaction which would change the number of available updates.

This bug was fixed in the package indicator-session - 0.3.91-0ubuntu1

---------------
indicator-session (0.3.91-0ubuntu1) precise; urgency=low

  * Backport "Don't lock the session when switching to another one"
    work from Robert Ancell, the screen locking is already done by
    consolekit and enforcing it there is problematic to i.e use the
    lightdm greeter as a lock screen (lp: #878836)
  * debian/control:
    - recommends python-aptdaemon.pkcompat so packagekit doesn't get installed
  * debian/source/format:
    - use v1, v3 doesn't play nicely with vcs backports

  [ Ken VanDine ]
  * New upstream release. (lp: #903756)
  * debian/control
    - added new build depends on libpackagekit-glib2-dev
