Thanks much Aaron. It worked.

Repeated the steps few times. Worked after doing this "apt-get autoremove openvswitch-datapath-dkms" and then repeating this step: kernel_version=cat /proc/version | cut -d " " -f3 apt-get install make fakeroot dkms openvswitch-switch openvswitch-datapath-dkms linux-headers-$kernel_version
