When you get the dialog for upgrading to Ubuntu 11.10 there is a button to "remind me later" that isn't doing anything when pressed.

Thank you for taking the time to report this bug to improve Ubuntu. Could you please try to run update-manager from a terminal if anything is logged? This might be a duplicate of bug #873595.

The exception shown in the terminal is :
Traceback:
