I had this issue and it ended up being licensed based.
In short I had entered an essential license before installing vcenter on the same esxi host.
So i just removed the license and it installed flawlessly.
Added them to the vCenter with its license and recuperated the essential license for another test server :-)
Reading these posts guided me in the right direction!
Great. I had the same issue and tried different approaches.
Reading your comment I got the idea to change the date of my ESXi host and windows machine to 2018 and it solved the issue, and set the dates back after the installation.
wow. it worked.
This is very useful tip. Many thank's to david.sjostrand.
Now is my case (sorry my English): between 2017 and 2017 I insatlled vcsa many times without big problems. 2019 after power crash I lost one of my vCenter's. I began install and meeted stuck (80%) problem. After reading david's post i did so:
- shutted down all VM's on target ESXi:
- manually set date on ESXi between sept. 2017 and sept. 2018 (my case); also i temporary deleted ntp settings;
- manually set date on my PC to be between sept. 2017 and sept. 2018;
- began installing vcsa; there's 2 variants (1: in installer settings set root os-password to default value "vmware" or 2: after installer stopped in a stuck (80%) log in to Photon-OS console with root/vmware and change root password to value you have set in installer settings)
