Vmware esxi : Could not find a trusted signer

During the installation of vSphere Installation Bundle (VIB) package I received the following error

esxcli software vib install -d "/vmfs/volumes/machines/megaraid_sas.zip"
('VMware_bootbank_scsi-megaraid-sas_6.601.55.00-1vmw.500.0.0.472560', 'Could not find a trusted signer.')
vibs = VMware_bootbank_scsi-megaraid-sas_6.601.55.00-1vmw.500.0.0.472560
Please refer to the log file for more details.

this is a result of following package which is not from trusted vendor, it’s from a third-party, we have to add “–no-sig-check”
option to proceed with the installation

esxcli software vib install -d "/vmfs/volumes/machines/megaraid_sas.zip" --no-sig-check
