strange dialog appears every now and then

[Oded Arbel]

I'm runing Ubuntu 12.04 (beta) and every so often a window pops up saying
"System Notification
Software updates are available"

And there are a Cancel and OK buttons.

When I click OK, a nautilus window pops up (I'm using Kubuntu, so its not something I'm used to see).

Running xdotool on the window, I get "window 32179936 has no pid associated with it." - which is really weird and as far I understand is against the X11 specifications.

This behavior is weird, and frankly - a bit annoying.

Screenshot showing the dialog.

The weird effect on the dialog's backgorund is because the dialog is semi transaparent (which according to my kwin settings probably means its a dialog and not a normal window) and it is disaplayed over a part of the background that has a sharp brightness change.

When it happened again this time, I went and started killing processes until the dialog went away. As far as I understand now, the process responsible for this dialog is /usr/lib/kde4/libexec/polkit-kde-authentication-agent-1 .

no idea where it comes from but that message is from a GTK application (KDE HIG define the approving button left and the rejecting button right, GTK is the other way around). Also the polkit binary you mentioned is nothing but an authorization helper, but certainly not the application creating the window etc.

Not a kubuntu-meta bug.

It looks like the dialog from unattended-upgrades. Assigning to that package

Unattended-upgrades does not have a GUI, it looks like update-manager.
