resolvconf error

Actually, for me it required to follow the following steps (I learned from launchpad, bug #324233):

Before:

$ ls -l /etc/resolv.conf
-rw-r--r-- 1 root root 30 2009-08-16 13:38 /etc/resolv.conf

$ sudo mkdir /etc/postfix
$ sudo touch /etc/postfix/main.cf
$ sudo rm /etc/resolv.conf
$ sudo ln -s /etc/resolvconf/run/resolv.conf /etc/resolv.conf
$ ls -l /etc/resolv.conf
lrwxrwxrwx 1 root root 31 2009-08-16 13:42 /etc/resolv.conf -> /etc/resolvconf/run/resolv.conf
$ sudo reboot

After:

$ ls -l /etc/resolv.conf
lrwxrwxrwx 1 root root 31 2009-08-16 13:42 /etc/resolv.conf -> /etc/resolvconf/run/resolv.conf
