RED007: Unable to verify Update Package signature

I have several systems returning this error now with different updates and it is frustrating:

R530: Serial-ATA_Firmware_HFKCX_WN64_GP46_A00.EXE

Components Disk 0-7 on Embedded AHCI Controller 1

Current GP45

Available GP46

All these updates are listed as Critical in Dell's OME (OpenManage Enterprise) and all fail to apply, both in OME as well as when directly uploaded to the iDRAC webUI. None of these servers run windows, so I can't simply run the DUPs on the host.
