Till, do you have files in /etc/apt/sources.list.d? This is likely where the packages sources would come from.
This bug comes from the fact that at some point (or maybe you still do) packages were installed from the ~network-manager team trunk PPA. The issue is in network-manager, not dhcp3, so I'm reassigning it as such. As for a quick fix, if you're on lucid try to do the following: sudo apt-get install network-manager=0.8-0ubuntu3 libnm- glib2=0.8-0ubuntu3 libnm-util1=0.8-0ubuntu3 network-manager- applet=0.8-0ubuntu3 This should take care of downgrading the network-manager packages to the correct versions (which don't require isc-dhcp (which should have been available in the ppa stated above though)). You will likely also want to run 'sudo apt-get autoclean' to make sure your package cache contains the right things -- 0.8-0ubuntu5~nmt5~karmic should then disappear from the output of apt-cache policy, but you will still need to make sure the ~network-manager/trunk ppa isn't listed in sources.list or files under sources.list.d/. ** Package changed: dhcp3 (Ubuntu) => network-manager (Ubuntu) ** Tags added: nm-trunk -- Recent update broke dhcp https://bugs.launchpad.net/bugs/643100 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dhcp3 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
