Nov 1 15:48:08 ubuntu partman: Found a dos partition table in /dev/sda10
It seems you have something that looks like a dos partition table in /dev/sda10. I'm guessing that mke2fs is printing that warning and then asking if you want to continue, and it never gets any input since it isn't actually connected to a tty. partman-ext3 probably needs to add a -F.
As a workaround, dd if=/dev/zero of=/dev/sda10 count=1 should clear it out.
I noticed this in the syslog:
