我尝试了校验和 Fedora Workstation 29 和 Fedora KDE Plasma，但它总是失败。我做错了什么，教程不完整还是服务器中的文件已损坏？
细节：
我在 Powershell 中使用 Windows -> 命令：
对于 KDE：
$image = "Fedora-KDE-Live-x86_64-29-1.2.iso"
$checksum_file = ""Fedora-Spins-29-1.2-x86_64-CHECKSUM"
$sha256 = New-Object -TypeName System.Security.Cryptography.sha256CryptoServiceProvider $expected_checksum = ((Get-Content $checksum_file | Select-String -Pattern $image) -split " ")[0].ToLower()
$download_checksum = [System.BitConverter]::ToString($sha256.ComputeHash([System.IO.File]::ReadAllBytes("$PWD\$image"))).ToLower() -replace '-', ''
echo "Download Checksum: $download_checksum"
Download Checksum: 5f7103a79e705bc1be95b7a2350b82cae857196542396cec0e3e7dfd7d16815a
echo "Expected Checksum: $expected_checksum"
Expected Checksum: #
if ( $download_checksum -eq "$expected_checksum" ) { echo "Checksum test passed!" } else { echo "Checksum test failed." }
Checksum test failed.
对于工作站：
$image = "Fedora-Workstation-Live-x86_64-29-1.2.iso"
$checksum_file = "Fedora-Workstation-29-1.2-x86_64-CHECKSUM"
$sha256 = New-Object -TypeName System.Security.Cryptography.sha256CryptoServiceProvider
$expected_checksum = ((Get-Content $checksum_file | Select-String -Pattern $image) -split " ")[0].ToLower()
$download_checksum = [System.BitConverter]::ToString($sha256.ComputeHash([System.IO.File]::ReadAllBytes("$PWD\$image"))).ToLower() -replace '-', ''
echo "Download Checksum: $download_checksum"
Download Checksum: 653cc283749100e9b46625d23938ff890ae29482bef142f5a0f99c5a5ddc03e9
echo "Expected Checksum: $expected_checksum"
Expected Checksum: #
if ( $download_checksum -eq "$expected_checksum" ) {echo "Checksum test passed!"} else {echo "Checksum test failed."}
Checksum test failed.
