I'm trying to install indigo to ubuntu 14.04.2, which is testing version of ubuntu trusty, but I met conflict with HWE packages from utopic as follows:

$ sudo aptitude install ros-indigo-rviz

HWE packages are needed to run ubuntu 14.04 in my hardware. How can I install indigo packages resolving the conflicts?
