Public bug reported: When installing over an existing installation (necessary if an update crashes half-way through :( ) and /etc/apt/apt.conf has the Default- Release set (eg, to "natty"), then the installer will quietly hang at "Saving installed packages".
I discovered what the problem was by: 1. booting from the install CD 2. selecting "Try Ubuntu" (rather than "Install Ubuntu") 3. opening a terminal 4. starting the installer with debug logging on; ie., ubiquity -d 5. this popped up a dialog indicating a system problem 6. looked at the intended report which complained that APT:Default-Release = "natty" was not in the repository I manually fixed it by temporarily mounting the root volume and deleting the ...../etc/apt/apt.conf file.
