Title:
  Update cache doesn't provide real progress information

Status in aptdaemon package in Ubuntu:
  Fix Released
Status in update-manager package in Ubuntu:
  Fix Released

Bug description:
  Since we cannot make any good assumptions about the download size of
  the repository meta data aptdaemon shows a pulsing progress
  information instead of a real progress.

  
  Original bug report:

  Binary package hint: update-manager

  This is not a major issue but does affect the user perception of update progress.
  Whan checking for updates the 'progress bar' behaves inconsistently, often going to 100% and then jumping back to (say) 50%. Using system monitor to check network activity also shows that although the status bar / progress box says (say) "downloading file 40 of 42", all network download activity has stopped and the software is presumably parsing the downloaded files.
  To improve user perception/experience I think that the operation of the progress bar should be improved to show a steady increase from 0% to 100%, without 'jumping back' to a lower value having already reached 100%. The status messages could also be improved to read (say) "Downloading file 10 of 42.." - "downloading file 42 of 42.." - "Processing files.."
  My system: Ubuntu Karmic on ASUS EEE900 - all latest updates applied as of today. Update Manager 1:0.124.8 - though this behaviour has existed since I started using Karmic.
