I don't have this problem but I'm using 10a432 so maybe that's the problem!

i've installed it once on an 6=8G usb flash drive from leo but it gave me the no packages erros when trying to repair permissions with disk utility.
i'm trying now to install from another usb flash drive to not have this erros and to test all the needed kekt...but it won't let me on mbr
