Hi,

I followed exact process explained and still checksum failed. Here is the detail:

1) Downloaded Fedora-Workstation-Live-x86_64-26-1.5.iso in Desktop
2) wget https://getfedora.org/en/static/checksums/Fedora-Workstation-26-1.5-x86_64-CHECKSUM to download Fedora-Workstation-26-1.5-x86_64-CHECKSUM Desktop.
3) curl https://getfedora.org/static/fedora.gpg | gpg --import

Did you just download the iso the one time? Did the byte size match the 1563426816 that was in the CHECKSUM file? It's entirely possible sha256sum is doing its job and successfully detected a bad download.

the most reliable method to download the ISO is via torrent. the torrent program automatically will automatically checksum the download as it goes. on completion it will be 100% correct for seeding purposes apart from your own usage.

Ok, first time my download was not complete due to internet interruption. Later, I downloaded couple of times which has same byte size as in checksum but still failed in each case with the same error.

again, try the torrent. also if the connection is interrupted it doesn't matter. the torrent can resume from where it left off.
