  • Please replace images of text with copy/pasted text. Read your output: Your problem seems clearly explained in the install -f output. That happens when you unwisely add non-Ubuntu sources that provide incompatible packages. This would be much easier to lead you through if we could copy/paste and highlight the important bits of your output.

sudo dpkg -P {defect package} helps to solve this problem. For more info about this problem read here: trying to overwrite '/usr/bin/opencv_haartraining', which is also in package libopencv2.3-bin 2.3.1+svn6514+branch23-12~oneiric
