Bug Description
Ubuntu Natty alpha 3
Ubuntu 12.10
When the installer is "Copying files", the installation progress bar fills up completely. When the copying has finished, the progress bar restarts from zero. This makes it much less useful, as it raises the possibility that the progress bar will restart from zero again some unknown number of times.
This was verified in usability testing of the Ubuntu 12.10 installer: three of three participants were surprised that the progress bar restarted from zero. For example: "The installation process is nearly finished, about 75%. Installing system? I’m actually taken to a new thing, I didn’t expect that. It will be nice to tell me the process. I don’t know how many stages, very frustrating, as I thought it was done. Then something else shows up."
Instead, the installation steps should be allocated estimated fractions of the progress bar so that it fills only once for the entire installation.

This is complicated by a number of things, chief among them debconf's inflexibility with respect to nested progress and the handoff between the core file copy phase (install.py) and the subsequent configuration phase (plugininstall.py).
