Comment 23 for bug 353278

OK. I reproduced the bug, and as with others, I get this error message:

Authentication as an administrative user is required.
The following users qualify as administrative users: skroon
Select user: Failed to obtain authorization for org.freedesktop.packagekit.system-update.
Authentification error : org.freedesktop.DBus.Error.NoReply : Message did not receive a reply (timeout by message bus)

Nothing was output to my ~/.xsession-errors , however.

I also ran polkit-auth as below, which didn't seem to have any problem:

skroon@mania:~$ polkit-auth --obtain org.freedesktop.packagekit.system-update
Attempting to obtain authorization for org.freedesktop.packagekit.system-update.
Authentication as an administrative user is required.
The following users qualify as administrative users: skroon
Select user: skroon
Password:

no
Successfully obtained the authorization for org.freedesktop.packagekit.system-update.

Finally, this problem went away for some reason on my second try yesterday, but has since come back. Not sure why.

@James: when adding your repositories above and running apt-get update, I get the following at the end:

W: GPG error: http://ppa.launchpad.net jaunty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY EB6DA76C6591493A
W: You may want to run apt-get update to correct these problems

(Ironically, it's recommending running the currently running program to fix the problem).

I'm hesitant to continue before sorting these warnings out.
