Comment (by garubi):

 Googling for the same problem, it looks like the problem is in
 {{{
  wp-includes/functions.php at line 1756
 }}}


 As I found on this support forum post(https://wordpress.org/support/topic
 /wordpress-installer-error/#post-13600170), this code checks if the tables
 in db already exist, and for some reason on some environments get a false
 positive:
 {{{#!php
 <?php
     $described_table = $wpdb->get_results( "DESCRIBE $table;" );
     if ( is_array( $described_table ) && count( $described_table ) === 0 )
 {
         continue;
     }
 }}}

 if you replace that with:
 {{{#!php
 <?php
 if ( ! $wpdb->get_results( "DESCRIBE $table;" ) ) {
     continue;
 }
 }}}

 the installer works just fine.
