I was trying to upgrade from 13.10 to 14.04 and it prompt out message about some required package couldn't be install and required me to sent this bug report. I am sorry I am quite newbies in linux system so maybe this report is not really a good question or it's not so detailed. Please do not hesitate to ask from me if any further information is required. Thanks for your help and patient.
