How do I verify my image?

Once you have downloaded an image, verify it for security and integrity. To verify your image, start by downloading the proper CHECKSUM file into the same directory as the image you downloaded.

Next, import Fedora's GPG key(s):

$ curl https://getfedora.org/static/fedora.gpg | gpg --import

You can verify the details of the GPG key(s) here.

Now, verify that the CHECKSUM file is valid:

$ gpg --verify-files *-CHECKSUM

The CHECKSUM file should have a good signature from one of the following keys:

  • CFC659B9 - Fedora 30
  • 429476B4 - Fedora 29
  • 9DB62FB1 - Fedora 28
  • DBBDCF7C - IOT 2019

Finally, now that the CHECKSUM file has been verified, check that the image's checksum matches:

$ sha256sum -c *-CHECKSUM

If the output states that the file is valid, then it's ready to use!
