With "auto eth0\niface eth0 inet dhcp" in /e/n/i and "[ifupdown]\nmanaged=false" in NetworkManager.conf, NM doesn't manage eth0, so if eth0 isn't brought up that's not a bug in NM.
Please comment out "auto eth0" and "iface eth0..." in /e/n/i and try again under Ubuntu 12.04. Does NM still not configure eth0? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/617764 Title: eth0 disconnected after boot even though "auto eth0" -- r8169 Status in “network-manager” package in Ubuntu: Incomplete Bug description: Binary package hint: network-manager Thing I noticed on my two computers running Lucid: Sometimes the network (cable) does not start automatically. I have to manually do "enable network" on the nm-applet. I put ================= auto eth0 iface eth0 inet dhcp ================= into /etc/network/interfaces but it still happens. This can be a serious problem if the computer runs as a server or head-less.
