I use up-to-date Debian testing (wheezy), amd64 port, with KDE.

For the last six weeks or so I have been getting the following error
message several times a day:

cannot fetch install sources
E: Error http:ftp.us.debian.org
wheezy InRelease
E: Error http://security.debian.org
wheezy/Updates InRelease

I searched Google for "cannot fetch install sources".  This phrase is
found only in the file gpk-enum.c.  This file is related to the package
"gnome-packagekit" which is NOT installed on my system.  My system does
have "apper", "packagekit", "python-packagekit", "packagekit-tools", and
some related packages.


uname -a gives:
Linux c-76-111-67-198 3.2.0-3-amd64 #1 SMP Mon Jul 23 02:45:17 UTC 2012

packagekit gives:

Hi!
Where do you see this error message? In the system tray? This might be
a message emitted by Apper.
Why can the sources not be fetched? Is there a problem with the
server, or aren't you connected to the internet? Usually, PK checks
for a working network connection before refreshing sources.
If you want to disable the automatic update checks, you can simply do
that in Apper's settings.
Cheers,

Hi!
Please do always CC this bug report, so we have a copy of your
messages in the BTS.
You see a black window? If this is Apper, you should see a
notification message. Do you maybe have GNOME-PackageKit installed?
(in an old version)
Can you maybe make a screenshot of this message?
Apper itself is not supposed to be run as root, so please don't do
that ;-) Apper will request required provileges using PolKit dialogs.
In a KDE session, Apper handles looking for updates, installing new
packages (and applications) and manages software sources. It also
notifies you about package management state changes. If you have other
tools, you might use them and don't need Apper - a better solution
would be finding out what is wrong with Apper/your system config.
The warning you described below is probably because you started Apper
as root - DBus has to work properly, otherwise KDE would not work.
Can you please execute
 $ pkcon refresh
(you might need to have packagekit-tools installed)
Do you see any error when running that command?
Regards,
    Matthias

"gnome-packagekit" is NOT installed.
I clicked on a grey circle with an "i" in it then took a screenshot. It
is attached.
