OK, it seems the problem is that it tries to mount a ufs partition that I have on the harddrive as read-write,
1. IMHO damn stupid , or put more politely, dangerous - if you just want to migrate settings.... why write ?
Is ubuntu doing some stuff with my files ???
2. Second who asked the installer to launch the migration assistant to lunch ? Assuming so many things on the end user
is certainly not healthy.

The installer should politly ask if I want to migrate settings from this partitions, and certainly not mount it in write mode.

The error I see:
Ubuntu kernel: ufs was compiled with read-only support, can't be mounted as read-write
Ubuntu migration-assistant: error: Failed to mount /dev/sda13

Exception during installation:

I'm not positive the migration-assistant issue with your ufs partition is the root cause of your installation failure, so I'll open a migration assistant task.

My installation finished successfully with sudo ubiquity --no-migration-assistant, so I am quite sure it is the migration assistant.
You are welcome to install ubuntu on a device with UFS partition and see if you bump into this issue. I am quite sure you will.
I am also quite sure that it is not so common that ubuntu is installed side by side along FreeBSD, after all, I admit FreeBSD is an esoteric OS.
