resolvconf: Error: /etc/resolv.conf must be a symlink Error and Solution

When I try to restart my BIND 9 server under Ubuntu Linux using service bind9 restart or service bind9 start command, I get the following error:
resolvconf: Error: /etc/resolv.conf must be a symlink
How do I fix this problem?

You can fix this error by tying the following command (open a terminal and login as root):
$ sudo -i
# cd /etc
# rm resolv.conf
# ln -s /etc/resolvconf/run/resolv.conf .

# service bind9 restart

Postfix Error

If you get the error as follows (postfix error along with the above error):
 * Stopping domain name service... bind9                                                                                                                                                                                              [ OK ]

Type the following command:
$ sudo -i
# cd /etc
# mkdir postfix
# touch postfix/main.cf
# rm resolv.conf
# ln -s /etc/resolvconf/run/resolv.conf .
# service bind9 restart
