I've this issue only when I start the installer from either an ISO or an unpacked ISO from my laptop.
On any other Server or Workstation the installer runs without any problem
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
Same thing, on RHEL8 had to install libnsl - `dnf install libnsl`
