Install Oracle 19c RDBMS on Oracle Linux 8 – avoid [WARNING] [INS-08101] Unexpected error while executing the action at state: ‘supportedOSCheck’

Oracle RDBMS 19c is now certified on Oracle Linux 8. Unfortunately the Oracle Universal Installer in Silent Mode fails when checking the OS version. My OS release:

Oracle Universal Installer in Silent Mode

The OUI installer in silent mode stops and shows this error message: [WARNING] [INS-08101] Unexpected error while executing the action at state: ‘supportedOSCheck’. There is no parameter available like -ignoreOS or whatever, but two workarounds.

Workaround 1

Set the OS parameter in your terminal to a previous version and re-start the Oracle Universal Installer.

Workaround 2

to

Save the file and re-start the Oracle Universal Installer.

In the OUI Graphical User Interface you can ignore the message which occurs when the installer starts:

Summary

The installation of the RDBMS software by GUI is not my favourite. I try to use the silent method whenever it’s possible. And with a small workaround, this can be successfully done with 19c on OL8.
