If this happens to you, probably the network manager overwrites your resolv.conf with settings from /etc/network/interfaces.
Solution:
Change the lines “dns-nameservers x.x.x.x y.y.y.y” and “dns-search xxx.local” in /etc/network/interfaces to your correct settings (or add the lines), and the problem should be gone.
