Yesterday I was struggling while publishing SQL updates to WSUS with SCUP.
I bumped into the following error message:
CabUtilities.CheckCertificateSignature File cert verification failed for
After long hours of searching for a solution I finally found one.
It seems that the default cab size limit of WSUS is 384MB.
So i found some powershell code to resize the maximum cab size to 1024MB.
$wsus = [Microsoft.UpdateServices.Administration.AdminProxy]::GetUpdateServer()
$size = $wsus.GetConfiguration().LocalPublishingMaxCabSize
Write-host "Current Max Size: " $size
$config = $wsus.GetConfiguration()
$config.LocalPublishingMaxCabSize = 1024
