Unable to install pmOS after #725

I followed the instructions in @PabloCastellano's commit message for #725, and get this failure when running pmbootstrap install right after:

I also tried completely clearing out my pmbootstrap working directory, but still experience the same failure.

Interestingly enough, the package it is looking for does exist under <pmb work dir>/pacakges/x86_64/qemu-user-static-repack-2.8-r8.apk.
