Downloaded Fedora-Workstation-netinst-x86_64-22.iso
at least 3 times.
Each time, I computed the sha256 sum of the iso image.
And each time it was different to the sum in the file
Fedora-Workstation-22-x86_64-CHECKSUM

To wit:

$ grep SHA256 Fedora-Workstation-22-x86_64-CHECKSUM
Hash: SHA256
SHA256 (Fedora-Workstation-netinst-x86_64-22.iso) = 
c9d22e708b21336582b19b336b7063fc4b882be4cf96d4d0693de07bd66c25e8
SHA256 (Fedora-Live-Workstation-x86_64-22-3.iso) = 
615abfc89709a46a078dd1d39638019aa66f62b0ff8325334f1af100551bb6cf

$ sha256sum Fedora-Live-Workstation-x86_64-22-3.iso
37a3a23f9d2d01dc2b47660fcd7611cb2474f94a11ff208f38a52e16cbb5b263 
Fedora-Live-Workstation-x86_64-22-3.iso

$ ll Fedora-Live-Workstation-x86_64-22-3.iso
-rw-r--r-- 1 jd jd 1161293611 Sep 18 16:21 
Fedora-Live-Workstation-x86_64-22-3.iso


Then I found out why.

I had downloaded it from the mirror:

http://mirrors.kernel.org/fedora/releases/22/Workstation/x86_64/iso/Fedora-Live-Workstation-x86_64-22-3.iso

whereas the iso image at:
http://download.fedoraproject.org/pub/fedora/linux/releases/22/Workstation/x86_64/iso/Fedora-Live-Workstation-x86_64-22-3.iso

computes the correct sha256sum.

Thought I would bring this up for others to avoid.
