Hi all, already patched the official sailfishx zip image, my thoughts about the procedure after 4 attemps:

1.- don't do this in windows due the script is for linux
2.- in ubuntu 18 doesn't work the procedure (I used ubuntu 14)
3.- if you want to use a virtual machine, use vmware player (latest version)
4.- always use the virtualbox and vagrant latest versions!

regards to all from CHILE!
