Till, this is weird -- it looks more and more that either you did not make a successful upgrade to Lucid, or that you have some incorrect package repositories in place.
The official network-manager for Lucid is 0.8-0ubuntu3 -- you are running 0.8-0ubuntu5~nmt5~karmic! Both wrong Ubuntu version and wrong maintenance level... and, it sounds, yours is not compatible with Lucid's dhclient3. I have no idea where you got it... can you please attach here your /etc/apt/sources.list? -- 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
