Well I've been trying to install linux deepin 2014 on my laptop for past few days. Installation went fine for a while but suddenly an error message pops up "Installation failed". I tried to find the problem in log file and the following error messages were shown in the log file (Output is abbreviated):

What could be the solution to this problem. Please Reply.

My first guess is a bad disc. Perhaps burn another disc, and if you did not do it last time, this time burn the image at the slowest speed. You may also want to check the md5sum to verify the ISO is not corrupted.
