Description Adam Stewart 2015-11-15 16:52:10 UTC
Description of problem:

I tried the instructions for verifying checksums on Windows (section 3.3.1) but ran into a problem.

Version-Release number of selected component (if applicable):

Fedora 23 iso download, Windows 10 computer

How reproducible:

Follow the instructions detailed in section 3.3.1 of the install-guide on a Windows 10 computer.

Steps to Reproduce:

1. Download the Fedora checksum file
2. Open a powershell session
3. Change to the directory containing the checksum file
4. Run the following commands:

> $image = "Fedora-Server-DVD-x86_64-21.iso"
> $checksum_file = "Fedora-Server-21-x86_64-CHECKSUM"
> $sha256 = New-Object -TypeName System.Security.Cryptography.sha256CryptoServiceProvider
> $expected_checksum = ((Get-Content $checksum_file | Select-String -Pattern $image) -split " ")[0].ToLower()
> echo "Expected Checksum: $expected_checksum"

Actual results:

"sha256sum"

Expected results:

"a91eca2492ac84909953ef27040f9b61d8525f7ec5e89f6430319f49f9f823fe"

Additional info:

The correct checksum is actually in the fourth and final position of the string after being split. I recommend replacing the [0] in the instructions with a [-1], assuming that you are able to recreate this problem. If not, let me know and I'll try to provide a more detailed report.
