Same in Lucid release.
I created a bootable live-USB of Ubuntu 10.4 netbook on partitioned USB stick /dev/sdb2. I tried installing to empty partition /dev/sdb3. The installer stops with message reported above "Failed to unmount partition" "The installer needs to commit changes to partition tables but cannot do so because partitions on the following mount points cound not be unmounted: /cdrom"
/cdrom has /dev/sdb2 mounted on it.
As all partitions have been pre-created, there is no need for ubiquity to make changes to the partition tables.
I repeated testing, getting the same error message, whether:
a) formatting the new partition /dev/sdb3, boot installed to /dev/sdb
b) not formatting the new partition /dev/sdb3, boot installed to /dev/sdb3
c) not formatting the new partition /dev/sdb3, no boot loader installed.
