Maybe this message has been given to me before and I just overlooked it, because surely I have connected since 2014-08-07. Anyway, I asked our server maintainer to upgrade to 14.04. He tried this morning, and it broke the WeBWorK installation. (He had taken a snapshot so we are back to 12.04 and doing fine.)Your current Hardware Enablement Stack (HWE) is no longer supported since 2014-08-07. Security updates for critical parts (kernel and graphics stack) of your system are no longer available.For more information, please see: http://wiki.ubuntu.com/1204_HWE_EOLTo upgrade to a supported (or longer supported) configuration: * Upgrade from Ubuntu 12.04 LTS to Ubuntu 14.04 LTS by running: sudo do-release-upgradeOR* Install a newer HWE version by running:sudo apt-get install linux-generic-lts-trusty linux-image-generic-lts-trusty and reboot your system.
Are there known issues with upgrading to 14.04?
