Further investigation, during the ServiceDispatcher installation the logfile says :
File: C:\Program Files\Qlik\Sense\HybridDeploymentService\appsettings.json; Won't Overwrite; Won't patch; Existing file is unversioned but modified.
Our current (Sept2018) appsetings.json file in this location doesn't hold the node :
"LocalBearerToken": {
"SigningAlgorithm": "RS256",
"Certificate": "./server.pem",
"PrivateKey": "./server_key.pem"
}
The Powershell script that is executed during the installation IS updated as per the log :
File: C:\Program Files\Qlik\Sense\HybridDeploymentService\Configure-Service.ps1; Overwrite; Won't patch; Existing file is unversioned and unmodified - hash doesn't match source file
I unpacked all installation files from the SchedulerDispatcher.MSI and took a peek at the updated Configure-Service.ps1 script. In this script they try to set 2 variables based on an object (appsettings) created from the unmodified/not-overwritten appsettings.json file:
$appsettings.LocalBearerToken.Certificate = "$localCertificatesLocation\server.pem"
$appsettings.LocalBearerToken.PrivateKey = "$localCertificatesLocation\server_key.pem"
As this node doesn't exist in the not-updated appsettings.json file, the Powershell script returns the error in previous post, returning in the MSI returning an error code and the whole rollback starts.
This evening, before trying the upgrade for a 4th time, I will modify the appsettings.json file to hold this LocalBearerToken entry in the current appsettings.json file. This should cause the Configure-Service.ps1 script not to throw an error and hopefully finished the installation succesfully. I will post the outcome.
