I suspect this is rather to do with duplicate lines in the progress
output as is seen with list updates.  At least list update duplicates
are due to the apt infrastructure sending the file through
decompression stages, which is considered a separate fetch.

Reading the apt-pkg/acquire.cc and apt-pkg/contrib/progress.cc is a
start.  If you are interested in resolving such problems you must
understand the implementation and workings of these classes.

Questions you can look at:
* does the list update duplicates issues still occur?
* why does it occur (for your information only, and to help in further
* does a similar process happen with package fetching?
* is that the issue here?
