[INS-08101] Unexpected error while executing the action at state: 'supportedOSCheck'


Cause - No additional information available.  
Action - Contact Oracle Support Services or refer to the software manual.  
Summary  - java.lang.NullPointerException


Now let’s move on to a solution/workaround for this error. To fix this error we have two workarounds.

Workaround 1. Temporary Fix: Execute the below command to validate OS version and then export CV_ASSUME_DISTID to the supported version of OEL for 19c. Here we are using 8.1. 

[oracle@DBsGuruN ~]$ cat /etc/os-release
NAME="Oracle Linux Server"
VERSION="8.4"
ID="ol"
ID_LIKE="fedora"
VARIANT="Server"
VARIANT_ID="server"
VERSION_ID="8.4"
PLATFORM_ID="platform:el8"
PRETTY_NAME="Oracle Linux Server 8.4"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:oracle:linux:8:4:server"
HOME_URL="https://linux.oracle.com/"
BUG_REPORT_URL="https://bugzilla.oracle.com/"
ORACLE_BUGZILLA_PRODUCT="Oracle Linux 8"
ORACLE_BUGZILLA_PRODUCT_VERSION=8.4
ORACLE_SUPPORT_PRODUCT="Oracle Linux"
[oracle@DBsGuruN ~]$ export CV_ASSUME_DISTID=OEL8.1
[oracle@DBsGuruN ~]$ echo $CV_ASSUME_DISTID
OEL8.1


Workaround 2. Permanent Fix: Edit file $ORACLE_HOME/cv/admin/cvu_config using any editing tool and add a new line CV_ASSUME_DISTID=OEL8.1, followed by saving the file.

[oracle@DBsGuruN db_1]$ vi $ORACLE_HOME/cv/admin/cvu_config
CV_ASSUME_DISTID=OEL8.1
[oracle@DBsGuruN db_1]$ cat $ORACLE_HOME/cv/admin/cvu_config | grep -i CV_ASSUME_DISTID
#CV_ASSUME_DISTID=OEL5
CV_ASSUME_DISTID=OEL8.1


Now you can launch the installer using the command without prompt any warnings/errors.

[oracle@DBsGuruN db_1]$ ./runInstaller
