@amolnater-qasource if I remember correctly, you ran some testing on SLES15, did you face a similar issue?

Hi @pierrehilbert

We have revalidated this issue on 8.16.1 production kibana cloud environment and had below observations.

• No issues are observed while installing RPM or tar agent on SLES15.
• Agents remain Healthy throughout.
• We do get this error while running enable command: failed to create symbolic link '/etc/init.d/rc2.d/S50elastic-agent': No such file or directory.
• However, when we actually run the agent enroll command, we observed no errors on SLES15.

Please find below screenshots for the same:

For existing issues:

• We had SLES15 issue on 7.17.27 which is fixed now. [Fleet]: Sles 15 Linux agents gets unhealthy with Endpoint Security integration on 7.17.27 #6519
• RPM issue with RHEL9 is also observed on latest 8.18.0 and 9.0-beta1 builds, reported here [Fleet] RPM agent becomes unhealthy after adding Elastic Defend Integration. #6574

Please let us know if we are missing anything here.
Thanks!
