Last week, VMware released a knowledge base article KB 95536, which includes a script for fixing the LCM service on SDDC Manager.
Due to an invalid index file that was recently pushed to the VMware depot, the LCM service on SDDC Manager has downloaded several incorrect upgrade bundles. This is the reason why the LCM service crashes and is unable to recover.
It’s recommended to run this script (with steps described in the KB article) even if everything appears to be fine. This issue affects all SDDC Managers connected to the VMware depot. It only takes 5 minutes to complete.
Please follow the steps described in that KB. Below you can find a screenshot with the result of running the script.
