I have a MacBook Pro running on Mountain Lion. I am trying to install the newest version of Ubuntu for power pc, and after trying to burn the ISO onto the dvd, it says it could not verify the ISO. What should I do?
There might have been a connection problem while downloading ISO, or while saving downloaded content to disk the operating system you are using may made a mistake, it happens from time to time. You can try re-downloading the ISO.
Also, before burning ISO to media check if md5sum of ISO is correct. Hashes are here.
First, check to make sure the ISO you downloaded isn't corrupted. In the Mac OS X command line, you can run the, MD5 command to get the checksum for the disk image:
You can then compare the result of the command against the expected result that is listed here: http://releases.ubuntu.com/12.04.2/MD5SUMS
If your image is correct, and you're still having problems, it's probably because ubuntu has been making disk images lately using a new hybridized file format that doesn't place nice with the Mac OS X operating system. Some users have found command line operations that will allow them to rebuild the ISO for Mac OS X, but I have yet find a bulletproof method. Try your luck starting here:
