I faced the same problem after upgrade to 9.10 - empty /etc/resolv.conf after reboot, ifdown eht0 && ifup eth0 resolves the issue.
I googled old bug 31057 which blames resolvconf package and in fact I noticed that I had this package installed. So I removed it and I am just to reboot to check whether it helps. -- keeps rewriting /etc/resolv.conf https://bugs.launchpad.net/bugs/435874 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
