Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we cannot begin to fix this without some additional information. Could you please post the output of the command "apt-cache policy network-manager" (without the quotes). To run this command, open a Terminal (Applications -> Accessories -> Terminal), enter the command there, and push Enter. Copy the resulting text and paste it here. Thanks in advance.
