hey guys, sorry for spamming but on FC32 and Win 10 1909 this is also broken as
Richard Hrkach Jr pointed out (I modified it slightly to make it more verbose)

PS C:\Users\darin\Downloads> cd $HOME\Downloads
echo "Loading resource necessary to calculate your checksum...Please hold..."
$image = "Fedora-Workstation-Live-x86_64-32-1.6.iso"
$checksum_file = "Fedora-Workstation-32-1.6-x86_64-CHECKSUM"
$sha256 = New-Object -TypeName
System.Security.Cryptography.sha256CryptoServiceProvider
Loading resource necessary to calculate your checksum...Please hold...
PS C:\Users\darin\Downloads> $expected_checksum = ((Get-Content $checksum_file
| Select-String -Pattern $image) -split " ")[0].ToLower()
PS C:\Users\darin\Downloads> echo $expected_checksum
sha256
PS C:\Users\darin\Downloads> echo $expected_checksum
sha256
PS C:\Users\darin\Downloads> $expected_checksum = ((Get-Content $checksum_file
| Select-String -Pattern $image) -split " ")[0].ToLower()

PS C:\Users\darin\Downloads> echo $expected_checksum
(fedora-workstation-live-x86_64-32-1.6.iso)

Something seems to have changed in the split, but I don't know anything about
powershell nor coding - so I don't know where to begin to look at fixing
this...
