Hi, after I d/l Fedora-17-x8664-Live-KDE.iso, I d/l the Fedora-17-x8664-Live-CHECKSUM into the same directory. Then I followed the rest of the clearly documented directions in the Fedora 'Verify your ISO Download.'

Several errors occurred, and the log is here:

The file i wanted to verify shows: OK. But there are two warnings at the end. In particular, I'd like to know what is going on in the sha256sum. Could someone help me with understanding what this is telling me?

Thanks & Cheers!

sha256sum: WARNING: 20 lines are improperly formatted

This warning comes from the GPG signature in the checksum file. It can be ignored. The GPG signature data is 20 lines of information sha256sum doesn't understand.

sha256sum: WARNING: 1 listed file could not be read

This warning is because the checksum file has two ISOs listed, you only have one of them (so it can't check the file you don't have).
