I have recently upgraded my ubuntu to 15.10 and eventually Ethernet names were changed. I don't have any problem with the names but whenever I reboot the system the Ethernet connectivity is lost. The problem is the that the Ethernet device doesn't come up itself so I have to manually run the command.
ip link set ens255f0 up.
In /etc/network/interfaces file, I put
iface ens255f0 inet dhcp
but it didn't help. Could anybody help how can I solve this problem?
P.S: This is not duplicate question to this as there is no mention of this issue. Network interface name changes after update to 15.10 - udev changes
