I just had this same problem, sudo was working fine until I clicked on the icon for "Wired network connection" and the manual configuration, then I edited the domain. This had upset sudo. When I reset back the domain (in a similar way) sudo started to work again. -- 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
