Upgrade Issue with Eveline

It appears that some users are having issues with their Eveline installations attempting to upgrade to Debian Wheezy

To avoid this, please run the following command in your terminal to lock your installation against Debian Squeeze

 sudo apt-get update && sudo apt-get upgrade
