Ubuntu installer - Unmount partitions that are in use?

I am working on the unattended-iso project, and seeing this message:

for the bots and search engines

The installer has detected that the following disks have mounted
partitions:

/dev/sda

Do you want the installer to try to unmount the partitions on these
disks before continuing? If you leave them mounted, you will not be
able to create, delete, or resize partitions on these disks, but you
may be able to install to existing partitions there.

Unmount partitions that are in use?

It happens whenever you already have a filesystem on say sda1. Workaround:

d-i preseed/early_command string umount /media || true

• Fix
• Link to the original solution
