@Yongzhi Pan: Let's get to the bottom of this. Please install
resolvconf, reboot, connect to VPN, check that /etc/resolv.conf is
wrong. Then send the output of
ls -l /etc/resolv.conf
cat /etc/resolv.conf
ls -l /run/resolvconf
ls -l /run/resolvconf/interface
for F in /run/resolvconf/interface/* ; do echo === $F === ; cat $F ; done
ls -l /etc/resolvconf/resolv.conf.d
for F in /etc/resolvconf/resolv.conf.d/* ; do echo === $F === ; cat $F ; done
and also say what you think the contents of /etc/resolv.conf should be.

Title:
Does not correctly write resolv.conf
Status in NetworkManager:
Unknown
Status in “resolvconf” package in Ubuntu:
Incomplete
Bug description:
Binary package hint: network-manager
I am using Network Manager to connect to my OpenVPN server. When I use
the openvpn command line client, DNS push is fine, resolv.conf is
updated to the pushed DNS servers (old lines gone). When I use NM,
resolv.conf is not written corretly. The OpenVPN server pushes 4 DNS
server, but only the first one is appended to resolv.conf. It should
remove the old lines and add the 4 servers from the OpenVPN server to
resolv.conf.
