I am attempting to manually update a 6.7 host by following the instructions here: VMware Knowledge Base
I shutdown all the VMs and put the host into maintenance mode.
I uploaded the zip archive to the host, and typed this command:
esxcli software vib update -d "/vmfs/volumes/5c12a113-d25e07fa-2b94-d094661cea6e/update/ESXi670-201901001.zip"
When I type this command I immediately get this error message:
Error: A general system error occurred: Internal error.
This error is, of course, completely useless.
I've done a lot of searching, but have found nothing even remotely close to my situation.
I don't have two hosts yet, so I have no other options for updating my host.
