I'm trying to apply the security patch on my ESXi 6.5 host using the vSphere Update Manager 6.5 and the process is failing with erro 15 (The host returns esxupdate error code:15. The package manager transaction is not successful. Check the Update Manager log files and esxupdate.log) anyone knows about this error? I've already did the troubleshooting removing large files from var/locker but the issue still happen.
The esxupdate.log showed me (Unrecognized file vendor-index.xml in Metadata file) and on vSphere event (could not stage image profile could not find a trusted signer). I'm trying to found the solution following this error.
