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 "Removing conflicting..." message appeared and the installer moved at a crawl while showing messages about "nouveau".
I worked around it by killing the installer process (ubuiquity) and then starting over and omitting the FAT32 partition. After that, the installer finished properly. -- 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..."
