On Ubuntu 10.04, I had a similar problem related to /etc/resolv.conf editting.
I checked #91890, https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/91890 I found that someone already gave a nice solution for working around this weird problem as below: Edit your /etc/resolv.conf for the nameservers you want. And then sudo chattr +i /etc/resolv.conf The the resolv.conf is locked and no program could change it. If you want to change it back to be editable sudo chattr -i /etc/resolv.conf BTW, I found an dns checking script with the path of /usr/lib/avahi/avahi-daemon-check-dns.sh For those who might be interested, I pasted the script here: https://photon.snipt.net/avahi-daemon-check-dnssh/ -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/284298 Title: MASTER cannot save "auto" connection without renaming the connection Status in “network-manager” package in Ubuntu: Fix Released Status in “network-manager” source package in Intrepid: Won't Fix Status in “network-manager” package in Baltix: New Bug description: In nm-connection-editor editing a wireless connection, selecting "System setting", and pressing "OK" does not work.
