Thank you for your response. Fortunately (or regrettably, depending on your point of view), the bug has disappeared on me. Earlier, when I restored the link from /etc/resolv.conf to /run/resolvconf/resolv.conf, no DNS worked, even though the syslog file showed that dnsmasq had received correct server IP addresses. But now: it works. Either I did something wrong earlier, or some update (running Beta, I run dist-upgrade daily) has fixed whatever the problem were.
Whatever has happened, I hereby withdraw any claim that this is really a bug in Kubuntu 12:10 Beta. (BTW, I am not allowed to set the attributes that you recommend - I get a mysterious error: "lsattr: Operation not supported While reading flags on /etc/resolv.conf". Preventing modification of /etc/resolv.conf would not be the solution anyway.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1048430 Title: "dnsmasq not available on the bus" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1048430/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
