Description of problem: During the installation from DVD on a PowerMac G5, a Python traceback showing a failure to import CongratulationWindow has occurred. This is following the ejection of the DVD. There are a long string of "I/O error, dev sr0" with associated other messages issued at the same time. Version-Release number of selected component (if applicable): How reproducible: completely Steps to Reproduce: 1. Install Fedora 16 from DVD 2. 3. Actual results: Fully installed, but final panel (either GUI or text) says "Congratulations" never appears and the installation stop. Expected results: Completed installation. Additional info:
Did you run media check before attempting to do an install? This message is indicative of read failures due to bad media.
Yes, I did and they (both) reported OK to use. The G5's are, naturally, old, so the drives may be failing. Wouldn't failing media produce the errors before the DVD is ejected?
Today, I burned a new DVD, and ran the media check on it. It was again rated OK to install. Next I did an text based installation so that I could easily switch between windows during a minimal install. Watching the console on which the I/O errors appear, I can report that there were no I/O errors reported until after the DVD was ejected at the final stage of the installation. This appears to me to be a logical rather than physical error.
See, this is the problem with these media read errors, though. When you did a text install, you caused different files to be loaded off the media which influenced the result. Also, unfortunately media check does an okay job but not necessarily a perfect job. It's more of a best effort attempt.
The same problem occurs with a graphical install. Since this is the third DVD all with the same problem, doesn't that point to another difficulty in the code rather than the media?
