I was able to reproduce using the following:
Manual
select vda - create empty - free space -create two partitions 1.8G, 345.5M, both primary/raid, /dev/vda1 has bootable flag
select vdb - create empty - free space -create two partitions 1.8G, 345.5M, both primary/raid, /dev/vdb1 has bootable flag

press 'Finish partitioning and write change to disk' accidentally

Configure raid: write change to the storage devices (both vda and vdb are listed)
Create MD Device (Raid 1, num active: 2, num spare 0, active devices are /dev/vda1 and /dev/vdb1)
Create MD Device (Raid 1, num active: 2, num spare 0, active devices are /dev/vda2 and /dev/vdb2)
Finish

set /dev/md0 as / and ext4 (everything else are defaults)
set /dev/md1 as swap

do you want to boot your system if your raid becomes degraded? yes
write changes to disk: yes

ubuntu (name)
ubuntu (username)
ubuntu (password)
ubuntu (use weak, yes)
encrypt home (no)
proxy (none)
no automatic updates
no extra packages
