It looks like you're directly chrooting to the rootfs downloaded by LXD,
this isn't supported and in this case, likely to fail due to the
recently introduced requirement on /dev/urandom for yum, which you
wouldn't have in your chroot unless you take care of setting up /dev,
/proc and /sys properly.
The command you ran would also have downloaded the container and shifted
it for unprivileged use, running stuff as real root through chroot will
mess up permissions.
