[Bug 410310] Re: update-manager inconsistent with download size

[Manfred Hampl]

The missing float conversion had the effect of cutting off the decimal
fraction of the size and has meanwhile been fixed.

There, however is a second part to this bug:
When doing an update with update-manager some numbers displayed on screen come from update-manager and some from apt.
And now apt is displaying the numbers with decimal kilos (K=1000), and update-manager is displaying the numbers with binary kilos (K=1024). Even if the float problem is solved, this still gives a difference in display of about 4.8% for Megabyte numbers. (see some more details in my comment #9 above and some of the attached pictures).

Before this bug is set to 'Fix Released' I would like to raise the
question if it would make sense to consistently use one and the same
factor for kilo/mega representation throughout all package management
programs. This could be done either by changing humanize_size to decimal
as well, or changing apt/apt-pkg/strutl.cc to binary, or even by totally
eliminating humanize_size and using also the apt subroutines in update-
manager.

As far as I can see there is even another weakness in humanize_size (at
least in older versions, I have not checked the most recent ones yet):
the localization of the decimal separator is not correct and always
displayed as '.' even in 'decimal point is comma' local settings as with
German language.

Title:
  update-manager inconsistent with download size

Status in Update Manager:
  Confirmed
Status in “update-manager” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: update-manager

  There are three places, where the update-manager states the download size of an update:
  -For every package itself
  -For all packages together
  -During download
  All 3 state different sizes of a download. (see attachment)
  This is also the case in Karmic.
