This problem continues amazingly in Lbuntu 16.10, 16.04.2 and Ubuntu 16.10
I say "amazingly" advisedly, as this bug has been around since at least Ubuntu
12.04 in 2012/04/11.
Consider renaming it Ubuntu based installers are cought in a loop at "Removing
conflicting operating system files..."
This issue occurred for me as well. I'm installing Ubuntu 12.04 on a
Samsung 7 Series laptop. I added a 100GB partition for / with a 500GB
partition for /home. But I also tried to add a third FAT32 partition
with the remaining 150GB. There was an error creating the FAT32
partition and then the
Unfortunately, we were not able to resolve this issue in time for the
release. Even when simulating some of the disk layouts attached, I don't
see the problem.
However, to help us track down the cause it would be extremely useful
if someone would list the *exact* steps they take to see this

Something doesn't make sense here. Aside from the fact that 'sleep' is

This is caused by the script /lib/partman/finish.d/10clear_partitions
when umount fails after deleting critical directories from the
(existing) target filesystem. There appears to be a race condition
between subshell commands which access the partition mounted on
/mnt/tmpmount, and the umount.

I don't think this bug has anything to do with ntfs. This bug is very
easily reproducible with ONLY a separate ext4 home partition, and no
ntfs partitions at all. Quite a serious bug as keeping your home
partition unformatted so you don't need to wipe all your data (for
example I have 100+ gigs of
Looking at this, it seems that mostly everybody with this problem has an
additional NTFS partition. So basically to reproduce it you need this
partition schema:

* One partition mapped to /home, no format
* One NTFS partition, no format
Makes sense?

In my case (comment #31) I didn't have any NTFS partition. It seems that

I had tried to format / as ext4 und mount /home as ext4 before the beta
2 (download on 04-10) got stuck. Both partitions are primary. The
mentioned workaround can't be a solution, because handling the /home
data is pretty dangerous in my mind. To me, this really is a severe
