I am trying to do a silent upgrade of the Qlik N Printing Server component.
I found document for Qlik Sense (works well) and managed to do it for Printing Engine and Designer.
But I'm hittig a wall regarding the Printing Server. The logs refer to a problem with an empty password file:
ERROR LaunchProcess: initdb: password file "C:\Program Files\NPrintingServer\Settings\pgsqlpwd.txt" is empty
I attempted to create that file with the DB password in it, but it didn't change anything, I still got that error. There may be a format inside the file that I don't know.
Has someone managed to get this to work? It would be nice to be able to upgrade this server during our weekly off-hour maintenance window automatically.
