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. e.g. commands run in a sub-shell, such as the several (rm -rf "$x" ...) have not fully exited before the umount was run.
I was able to work around this by inserting 'sleep 5' before the umount $tmp on line 82. Not an elegant solution, but it worked for me. There are three umounts in this file, on line 82 (for /) on line 93 (for /home) and line 106 (for /usr/local), the other two probably have the same problem, which is why people above were seeing this when trying to preserve /home too. Attached is a patch which inserts a 1s delay before each of the three umounts. If that doesn't work for you, try increasing the delay. A better solution would be to not use subshell commands like () in this script. ** Patch added: "Add 1s delay before umount so subshell processes on mounted partition can exit" https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/946663/+attachment/3072460/+files/10clear_partitions.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/946663 Title: Installer stuck at "Removing conflicting operating system files..."
