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@olten dbhome_1]$ cat /etc/oracle-release Oracle Linux Server release 8.2
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.
export CV_ASSUME_DISTID=OEL7.8
Workaround 2
Edit the file cvu_config which is located in $ORACLE_HOME/cv/admin, change the line from
# Fallback to this distribution id #CV_ASSUME_DISTID=OEL5
to
# Fallback to this distribution id CV_ASSUME_DISTID=OEL7.8
Save the file and re-start the Oracle Universal Installer.
Et voilà
Some moments later… the WARNING message about the inventory can be ignored. OUI has created there some files from the previous attempt.
Launching Oracle Database Setup Wizard...
[WARNING] [INS-32047] The location (/u01/app/oraInventory) specified for the central inventory is not empty.

Oracle Universal Installer in GUI Mode
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.
