Bug Description

I have started setup and looks very good start. It asks for my details, password.
Than all file copy finished and started to setu GRUB and user data. I haven't set any profile copy (when it ask) but still it stop at profile copy and asking me that my /dev/sda11 partition is mounted and it cannot do next step. There is two buttons "Go back" and "Continue" . This is the error:

migration-assistant needs to mount a partition, but cannot do so because the following mount point could not be unmounted:


Please close any applications using these mount points.

Would you like migration-assistant to try to unmount these partitions again?

- When I click "Continue" it asks same question again.
- When I click "Go back" than setup stop and giving me message that setup done successfully with two buttons for Try Session or Restart.
- when I restart, GRUB giving error as there is broken setup.
- I have tried this by direct setup (when it first ask to start live session of SETUP now) and both giving me this error. (inside live session and direct setup)

NOTE: The partition /dev/sda11 is EXT4 partition.
