Exchange Server 2013 Update from to CU3 to CU8 stuck, Exchange completely down

Question

Hello,
We tried to update a Exchange 2013 server to CU8 because we needed support from Microsoft (certificate revoked, so OWA not working anymore) and they could only help us after updating to CU8 first. The problem is that the update got stuck and now Exchange
is not working at all anymore. Since it is a production enviroment and there is mail in all outboxes we do not want to turn back to a snapshot but solve the problem and continue the update. Any help is welcome because all mail is down now :-(
The error we received at the Exchange Server is:
C:\Users\administrator.DOMAINNAME\Downloads\Exchange-cu8>setup.exe /m:upgrade /In
stallWindowsComponents /IAcceptExchangeServerLicenseTerms

The Exchange Server setup operation didn't complete. More details can be found
in ExchangeSetup.log located in the <SystemDrive>:\ExchangeSetupLogs folder.

Hello Gadget,
Please find the solution as follows
This error is concern about WMSVC certificate which was deleted, we could refer to the following steps:
1- Go to IIS Manager and select server certificate,
2- Select “Create Self-Signed Certificate”,
3- For Server 2012 in the Friendly Name Field type: WMSVC and select the personal (certificate Store),
4- Now go to ” Management Service”,
5- From SSL Certificate choose the newly create “WMSVC” Self-Signed Certificate,
6- Apply,
7- Now  start service of “Web Management service”.
