  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.
