This bug seems to be weird to reproduce. My physical Xenial server worked for months without the proposed patch then last week it suddenly stopped receiving DHCP lease 2 days ago. After much troubleshooting I remembered I was on this bug report, used the proposed patch, and it works like a charm. Without it my server would never try to get a DHCP lease on startup but ifup worked fine once the machine was up.
I tried to recreate using a VM but the VM has no such issue; it grabs a DHCP lease without any problems. I don't know if it's some weird race condition or what.
