Hi Michael, > How do you configure your network? Do you use ifupdown vi > /etc/network/interfaces and if so, is the interface marked as auto or > allow-hotplug.
this is quite new installation which uses NetworkManager. So my /etc/network/interfaces configures just lo: $ cat /etc/network/interfaces auto lo iface lo inet loopback It don't use ifupdown: $ cat /etc/NetworkManager/NetworkManager.conf [main] plugins=ifupdown,keyfile [ifupdown] managed=false It's configured via file /etc/NetworkManager/system-connections/Wired\ connection\ 1. I have another Debian installation with systemd 204-10, where I use /etc/network/interfaces and don't have NetworkManager: $ cat /etc/NetworkManager/NetworkManager.conf auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp allow-hotplug eth0 iface br0 inet static address 127.0.1.1 netmask 255.255.255.0 bridge_ports eth0 Both installations didn't have a problem with upgrade.
