I am getting the same problem , however in my case when I press on the CHECK button, the application hangs and I cannot stop it not even with Control C from the terminal. I tried it from both Gnome3 and Gnome Classic sessions. Note: I just install Ubuntu 11.10 Oneiric 64Bit
Here is the error message: $ update-manager (update-manager:15521): Gdk-CRITICAL **: gdk_window_get_pointer: assertion `GDK_IS_WINDOW (window)' failed (update-manager:15521): Gdk-CRITICAL **: gdk_window_get_pointer: assertion `GDK_IS_WINDOW (window)' failed (update-manager:15521): Gdk-CRITICAL **: gdk_window_get_pointer: assertion `GDK_IS_WINDOW (window)' failed (update-manager:15521): Gdk-CRITICAL **: gdk_window_get_pointer: assertion `GDK_IS_WINDOW (window)' failed (update-manager:15521): Gdk-CRITICAL **: gdk_window_get_pointer: assertion `GDK_IS_WINDOW (window)' failed (update-manager:15521): Gdk-CRITICAL **: gdk_window_get_pointer: assertion `GDK_IS_WINDOW (window)' failed When I press CONTROL C I Get: ^CTraceback (most recent call last): File "/usr/lib/python2.7/dist-packages/UpdateManager/MetaReleaseGObject.py", line 42, in check def check(self): KeyboardInterrupt But has no effect!!! As a work around, I am using apt-get utility from the terminal. I hope it will be fixed soon.
