[ros-users] How do I resolve ROS Fuerte installation error

I was installing ROS Fuerte using Ubuntu Precise 12.04 and the following error occurred:

Processing triggers for install-info ...
Errors were encountered while processing:
/var/cache/apt/archives/yaml-cpp_0.2.7-5precise-20120502-0513-+0000_amd64.deb
/var/cache/apt/archives/libassimp-dev_2.0.863+dfsg-2_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)


What shall I do?
