Sounds like the prior lease wasn't released while shutting down and
rebooting.

How's your DHCP server assigning the IP, have you fixed it to that IP,
or that's just the currently used one?

If you fix an IP to a MAC, then it should assign the same IP to that
MAC, every time.  But, if it's auto-assigning some IP to some MAC,
booting up with a different OS may be seen by the server as a different
device.  The MAC isn't the only unique-identifier used by a DHCP server.

What's your DHCP server running on?
What says it finds a duplicate entry?  (The DHCP server, the DHCP client
in the upgrade?)
