Ubuntu

unmount_active option is ignored

Asked by Julen Larrucea

The installation with preseed of Ubuntu 16.04 server (and previous versions), on a KVM virtual machine keeps showing the message:

'''
The installer has detected that the following disks have mounted partitions
/dev/vda
Do you want the installer to try to unmount the partitions on this disk before continuing? If you leave them mounted, you will not be able to create, delete or resize partitions on this disk, but you may be able to install to existing partitions there.
Unmount partitions that are in use?
'''

I do have the option:

d-i partman/unmount_active boolean true

and
d-i preseed/early_command string umount /dev/media
(also tried with)
d-i preseed/early_command string umount /dev/vda
d-i preseed/early_command string umount /dev/vda1

Is this a bug, or am I missing something?

Did you mount and manipulate the partitions on the storage prior to kicking off the installer?

No, I didn't. The disk is clear and freshly created. But, the unmount_active, should unmount whatever there is, no matter if it was partitioned or not...
