Clearlinux version: 28100 (Desktop-version) & are present in the /usr/lib64/ directory
Cannot upgrade OS version as it is the requirement.

how to upgrade the libraries without updating the OS?

If you’re doing your own mix, you have to provide all of the packages and dependencies that differ from the base version you’re running the mix from. You would need to provide the updated libevent and libtelemetry source object library files as part of the mix.
