I did get some errors when trying to install this, but I copied the vmlinuz and initrd to /boot/firmware and I can get an ip now.
I retried the install and still get the errors, here's the log of that: ubuntu@ubuntu:/mnt$ sudo dpkg -i linux-image-4.15.0-1029-raspi2_4.15.0-1029.31_final1_arm64.deb (Reading database ... 61742 files and directories currently installed.)
