How to work around error [INS-08101] Unexpected error while executing the action at state: ‘supportedOSCheck’

Thanks so much to Martin Berger for his blog post showing how to work around an error that shows up when you attempt to install Oracle 19c software on a RHEL8 distribution.

I wanted to install Oracle software on a RH8.5 Linux server:

cat /etc/redhat-release
Red Hat Enterprise Linux release 8.5 (Ootpa)
  

This is the error I received:

    

In my case, the only thing I had to do was to add another environmental variable:

export CV_ASSUME_DISTID=OEL7.8

Execute the installer again and you will see a different screen:

./runInstaller
