I did not alter any configuration after the upgrade, I just need to maintain the 15.10 functionalities. I have done several reboots with no luck.

Update1: I purged samba and tried to re-install, but got the following error:

Errors were encountered while processing:
samba
E: Sub-process /usr/bin/dpkg returned an error code (1)
Failed to perform requested operation on package. Trying to recover:
Setting up samba (2:4.3.8+dfsg-0ubuntu1) …
Job for smbd.service failed because the control process exited with error code. See “systemctl status smbd.service” and “journalctl -xe” for details.
invoke-rc.d: initscript smbd, action “start” failed.
dpkg: error processing package samba (–configure):

Processing triggers for libc-bin (2.23-0ubuntu3) …
Errors were encountered while processing:

解决方案：

1. $ vim /etc/samba/smb.conf
2. 找到 security = share 并将其注释掉
3. $ systemctl restart smbd.service
