Bug 990744 has something to do with how extended partitions are treated as locked. This bug is reproducible when an extended container partition with a swap partition inside is present on disk.
After reformatting the drive through GParted live: 1. Delete main ext4 partition 2. Delete swap partition inside the extended container. 3. Delete extended container partition.
The container partition will not permit itself to be formatted until the swap partition inside is cleared. After using these steps, the installation successfully completed.
Very user-unfriendly when installing and selecting "ERASE ENTIRE DISK", knowing the implications. Anyway to instruct the installer to bypass the lock and force format?
The ubiquity bug, whatever report is the correct one, is still alive and prevents installing in laptops with battery.
