splunk soar GLIBC.2 not found error

[mory]

Hi,

I am trying to install Splunk SOAR (On-premises) as an unprivileged user on CentOS 7.9 and when I am running ./soar-prepare-system script I get the following error message:

./usr/python39/bin/python3.9: /lib64/libc.so.6: version `GLIBC_2.25' not found (required by /opt/splunk-soar/usr/python39/bin/../lib/libpython3.9.so.1.0)
./usr/python39/bin/python3.9: /lib64/libc.so.6: version `GLIBC_2.26' not found (required by /opt/splunk-soar/usr/python39/bin/../lib/libpython3.9.so.1.0)

 I tried to install it on CentOS 8 and got another error said

Unable to read CentOS/RHEL version from /etc/redhat-release.

 Any sugestions?

The first error could appear if you 're trying to install a RHEL8 version of Soar on a Centos7.

Regarding CentOS 8, it's not officially supported but you can download a version CentOS/RHEL8...
