[Bug 732634] Re: Progress bar restarts from zero after copying files

[Matthew Paul Thomas]

** Description changed:

- Binary package hint: ubiquity
- 
  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.

Title:
  Progress bar restarts from zero after copying files

Status in “ubiquity” package in Ubuntu:
  Confirmed

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.
