This may be a bug in apt-get or cupt, I'm not sure. But the same command on both produces different predictions on the downloaded and installed size of the same set of packages: The following 9 packages will be INSTALLED: iceweasel libmozjs1d libnspr4-0d libnss3-1d libstartup-notification0 libxcb-atom1 libxcb-aux0 libxcb-event1 xulrunner-1.9Given the small differences, I cannot try to verify this on my system, so let's verify the result on yours. Let's do 'cupt show iceweasel libmozjs1d libnspr4-0d libnss3-1d libstartup-notification0 libxcb-atom1 libxcb-aux0 libxcb-event1 xulrunner-1.9 | grep ize' and summarize sizes by hand (xcalc, bc -q etc.) to see which package manager is not right.
This looks like a bug in apt. Observe:
d...@skynet:~$ echo "(+ $(apt-cache show iceweasel libmozjs1d libnspr4-0d libnss3-1d
libstartup-notification0 libxcb-atom1 libxcb-aux0 libxcb-event1 xulrunner-1.9 | grep
^Size | awk '{print $2}' | xargs))" | ypsilon -m
10418344 So apt itself agrees that the expected Size of these packages is 10418344 Bytes.Now, the question is, should apt say there are 1024 bytes in a kilobyte, or 1000? Apt currently does the latter and truncates this to 10.4 MiB. I believe the former is more proper, and it should reconvert this to 9.94 MiB.
Note that other UNIX tools, like "free", also follow the former convention like cupt. Regards, Daniel -- Daniel Moerner <dmoer...@gmail.com>
