Introduction:

While trying to install oracle database 19c on Linux/OL 8 through Oracle Universal Installer in GUI as well as silent mode in Linux or Oralce Linux that stops and shows this error message: [WARNING]: INS-08101 Unexpected error while executing the action at state: ‘supportedOSCheck’. In this guide, we’ll walk you through understanding the error, and more importantly, provide steps to resolve the issue.

Environment:

Oracle Linux 8.x / RHEL 8.x

Cause:

oracle Linux 8.9/RHEL 8.4 is not supported by the oracle linux client in the downloads file due to that issue “INS-08101” happened at the start of Oracle database 19c installation.

Resolution:

INS-08101 Unexpected error means that there’s no CV_ASSUME_DISTID, an environmental variable set by the verification program, which is an unexpected situation.

Method 1: (Temporary)

To solve this error ‘supportedOSCheck‘, set the parameter in the terminal to any previous version like OEL7.6 , with Export and run the runInstaller.

[oracle@oraclelinux ~]$ export CV_ASSUME_DISTID=OEL7.6

Method 2: (Permanent Solution)

Edit the cvu_config file under $ORACLE_HOME/cvu/admin with following path in the terminal and change the below line:

[root@oraclelinux ~]# sudo nano /u01/app/oracle/product/19c/dbhome_1/cv/admin/cvu_config

and change the below line from to.

From

#Fallback to this distribution id
CV_ASSUME_DISTID=OEL5

#Fallback to this distribution id
CV_ASSUME_DISTID=OEL7.6
