installation problem

[us3r1723]

when I try to install the system it gives the error in the terminal: "chcon: failed to get security context of /..."
and when it starts to install the packages a pop-up opens with the error message:
"Packege maneger error
the packege manager could not make changes to the installed system. the command
pacman -S --noconfirm Linux linux-headers base-devel
returned error code 1"
I tried it on both virtualbox and hard drive
what can i do to solve that?
