Description of problem: I have downloaded the FC 15 install iso files and the checksum file and the netinst file. Then I run sha256sum -c Fedora-15-i386-CHECKSUM and get a non-match condition for the main .iso image. Version-Release number of selected component (if applicable): Fedora core 15 How reproducible: I've tried several different mirrors with the same results. Steps to Reproduce: 1.download all 3 files 2.run sha256sum -c Fedora-15-i386-CHECKSUM 3.observe error messages. Actual results: sha256sum -c Fedora-15-i386-CHECKSUM Fedora-15-i386-DVD.iso: FAILED Fedora-15-i386-netinst.iso: OK sha256sum: WARNING: 20 lines are improperly formatted sha256sum: WARNING: 1 computed checksum did NOT match clipper bash-4.1 /export/home/isos# l total 3765576 drwxr-xr-x 2 root root 4096 Aug 4 22:03 . drwxr-xr-x 16 root root 4096 Aug 3 22:10 .. -rw-r--r-- 1 root root 1112 May 24 14:22 Fedora-15-i386-CHECKSUM -rw-r--r-- 1 root root 3650455552 May 13 12:59 Fedora-15-i386-DVD.iso -rw-r--r-- 1 root root 205471744 May 13 12:58 Fedora-15-i386-netinst.iso Expected results: OK for the Fedora-15-i386-DVD.iso file.

The sizes and timestamps on your 3 files look correct. Suggest running rsync on Fedora-15-i386-DVD.iso to try repairing it. In the same directory, run touch Fedora-15-i386-DVD.iso (so rsync doesn't just assume the file is correct since the timestamps match) rsync -avzP dl.fedoraproject.org::fedora-linux-releases/15/Fedora/i386/iso/Fedora-15-i386-DVD.iso . (note the trailing .) I had an existing copy of the i386 F15 DVD ISO and verified that the version of the file I rsync'ed using the above commands matched the checksum.
If you still can't match the checksum after trying the above, look into hardware problems at your end - for example, try running memtest. This is more likely especially since you say you experienced it on several different mirrors. Although it can happen, the chances of it happening on more than one attempted mirror is pretty low.
