The installation proceeds normally until the console log gets to:
Module 'Magento_Weee': Installing data...
At this point (73%) the user experience just hangs, while the browser repeatedly requests prolong and unlogin. It appears that at this point in the installation, a cookie
admin is issued with an expiration date set in the past - This installation is on Centos/Cloudlinux 7 with Litespeed.
Can anyone hazard a guess at why this may be happening?
