I have been using Ubuntu on VMware Player; today when I logged into VMware, it showed updates available for Ubuntu 15.xx. I allowed the updates and after downloading all the packages it restarted automatically, but never booted back. It is throwing messages like

```
Piix4_SMBus: 000:00:07.3: Host SMBus controller bus not enabled
failed to start /etc/rc.local compatibility

```

Please describe a way to fix it!
