Hello, 

Please login to your WSUS server and check the below configuration.

  • Run the MMC > Snap-in certificate > computer 
  • Check the WSUS folder if it contains the private key of the code signing certificate. If this doesn't have a private key or just a public key, then delete the certificate from WSUS. 
  • Login to the IE as an administrator ( Right-click run as admin) and open SVM. 
  • Go to Patching WSUS/ system center and try to create an install certificate, if you receive an error while creating a certificate then follow the below steps. 
  • Microsoft has disabled the feature enabling the creation of a WSUS self-signed certificate on Server 2012 R2.
    While Server 2012, 2012R2, 2016 - WSUS will not generate self-signed certificates by default, it is possible to restore the legacy behavior by setting the following registry key:
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Update Services\Server\Setup\
  • Create DWORD value: EnableSelfSignedCertificates = 1
  • Try to create a certificate again. 
  • If you do have the private key of the code signing certificate in the WSUS folder then check the pubic key of that certificate in trusted root and trusted publishers. 
  • After checking all the things, Please try to create a  package and publish it to your WSUS server. 

We hope this will resolve your issue. 

Regards,

Rahel
