Identical issue, namely you cannot progress without having a DHCP server and configuring a manual IP crashes the installation process and it starts over. However, I have experienced this on both VMware and a bare-metal HP ProLiant installations.
For reference (until such time an ISO is released with the above supposed fix) use 18.04.1 to install the operating system and dist-upgrade to 18.04.2 after the fact.
Unfortunately, 18.04.1 has been removed from http://releases.ubuntu.com/18.04/ leaving you finding a copy on more questionable sites.
