To what version of ESXi are you attempting to deploy?
VMware vCenter Server 6.7U1 b to a ESXi 6.7U1 host
Even though you say it runs without a problem, compare the checksum of the ISO and make sure it matches the one posted to ensure there's no corruption.
That's the funny thing about it, if I copy over the same ISO to another server or desktop it works just fine :smileyplain:
On RHEL8 this solved it for me:
dnf install libnsl
This solved my problem on fedora
dnf install libnslSame thing, on RHEL8 had to install libnsl - `dnf install libnsl`
