I’ve one BareMetal C1 instance that was originally installed from the Ubuntu 14.04 LTS image, then upgraded to 16.04 LTS and now to 18.04 LTS.
I’ve a problem that it fails to reboot cleanly: systemd decides to stop firstname.lastname@example.org, which runs /sbin/ifdown eth0, which makes the nbd device mounted on / unreachable, causing all sorts of fun errors and timeouts – and I have to go to the cloud console and do a hard reboot.
I had this problem after an upgrade to 16.04 LTS and ‘systemctl mask networking’ fixed it.
Now the problem is back and I’m running out of ideas how to fix it. Things that do not work:
- systemctl mask networking
- adding ‘no-auto-down eth0’ to /etc/network/interfaces
- adding ’ down false’ after ‘iface eth0 inet dhcp’ in /etc/network/interfaces
