[Bug 717243] [NEW] vlan interface won't start with ifup, can be started manually
You have been subscribed to a public bug: Binary package hint: vlan After rebooting my system yesterday, my vlan interface did not come up. I know that update-manager had been upgrading packages several times since the last reboot before that, but I don't know which ones were updated. I have this in /etc/network/interfaces: auto lo iface lo inet loopback auto eth0.20 iface eth0.20 inet dhcp this configuration had been working fine for several months before the problem started.
