Is your Raspbian Jessie or Stretch? If you are not sure give following command.
cat /etc/os-release
See below the output generated when I issued this command on Debian Jessie OS on Chip.
chip@chip:~$ cat /etc/os-release PRETTY_NAME="Debian GNU/Linux 8 (jessie)" NAME="Debian GNU/Linux" VERSION_ID="8" VERSION="8 (jessie)" ID=debian HOME_URL="http://www.debian.org/" SUPPORT_URL="http://www.debian.org/support" BUG_REPORT_URL="https://bugs.debian.org/"
