[2025-02-25 16:01:42] Error: Failed to run yum update

Root cause:

Certain images deployed on the Azure platform may include different versions of the libstdc++ packages.
In some cases, the presence of a newer libstdc++ version causes the upgrade script to fail when attempting to upgrade dependent packages, specifically, the clang package, which depends on gcc-c++ and libstdc++ packages.

Resolution:

Downgrade the libstdc++ package version to the required version and then try to re-run the upgrade script.

yum downgrade libstdc++-8.5.0-15.el8

Note: Take a VM snapshot before downgrading the package.
