Using Kickstart, once I get to the final installation screen I get:
/home/customer/www/../public_html/installation/platform/models/joomlasetup.php::L1014
#0 /home/customer/www/../public_html/installation/platform/models/joomlasetup.php(1014): substr(Array, -6)
#1 [internal function]: AngieModelJoomlaSetup->{closure}(Array)
#2 /home/customer/www/../public_html/installation/platform/models/joomlasetup.php(1025): array_map(Object(Closure), Array)

#4 /home/customer/www/../public_html/installation/platform/models/joomlasetup.php(55): AngieModelJoomlaSetup->updateAdminToolsParams()

I checked: https://www.akeeba.com/support/site-restoration/40509-substr-argument-1-string-must-be-of-type-string-array-given.html
Not sure if this is a bug?
