VMWare ESXi: Could not find a trusted signer

While connected to the ESXi host via SSH to install the LSI MegaRAID vib, saw the error “Could not find a trusted signer”

# esxcli software vib install -v /vmware-esx-provider-lsiprovider.vib
[InstallationError]
('LSI_bootbank_lsiprovider_500.04.V0.30-3000000', 'Could not find a trusted signer.')
vibs = LSI_bootbank_lsiprovider_500.04.V0.30-3000000
Please refer to the log file for more details.

just add '--no-sig-check' to the end of the install command – problem solved!

# esxcli software vib install -v /vmware-esx-provider-lsiprovider.vib --no-sig-check
