Please confirm whether UIM robot is compatible with Redhat9 version?
Also please confirm whether it is compatible with Ubuntu 22.x?
Robot released with DX UIM 20.4 CU4 supports RHEL 9 and Ubuntu 22 already (robot 9.36).
With CU4, for Robots, UIM has switched to GLibC based certification which means going forward any newer version of linux distro released would be implicitly certified in case Distro supports particular gLibC
Please see links below
Your UIM 20.4 installation does not need to be on CU4 to take advantage of the CU4 robot release with the newer linux operating systems. Probes are certified with new operating systems via their normal probe cadence update process.
