I am running Ubuntu Server 16.04. This server gets rebooted few times a day due to one of my long running process failing and bash script recovering things, by simply doing reboot.
After few days of such a setup there is no networking, on start I get: "failed to start raise network interfaces". I've connected keyboard and screen, logged in to the machine and noticed that /etc/network/interfaces has reference to enp2s0, however ifconfig returns the enp9so. I've changed that in /etc/network/interfaces so it matches enp9so and rebooted server. It has worked, however I can't figure out why it has happened?
I am not sure if this helps, but all (3) machines in this LAN network had some network problems as well, I am not sure if they are victim or the cause of this issue.
Restarting the other machines didn't help. I had to restart the switch and the router that this switch is connected to.
Any idea why I am experiencing this issue? Thanks
