So I've followed just about all tips, and none prove fruitful to me. The following is a copy of my /etc/hosts file: 127.0.0.1 scotty 127.0.1.1 scotty-laptop # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts Now when I try to run sudo commands from the shell, they produce the typical: sudo: unable to resolve host But I can still edit files. In fact, it produced that when I did a: sudo nano /etc/hosts yet I was able to modify it, and save it (and yes, it did save). Yet I still cannot run GUI administrator tools (change the time, system settings, etc...). Any ideas? -- sudo: unable to resolve host HOSTNAME https://bugs.launchpad.net/bugs/203593 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
