Indeed, why are some of those names different? The difference I found
was that sometimes an [0-9]%3a is inserted:
$ apt-get -qq --print-uris dist-upgrade|sed "s=.*/==;s/'//;s/.%3a//"|\
awk '$1!=$2{print $1,$2}' #eliminated the differences with ^^^^^^^^
But why the need to be different? I'm following
/usr/share/doc/apt/offline.html/ch3.html .
The difference is the epoch. %3a is the escape code for ":". When the upstream versioning becomes screwy for whatever reason, an epoch[a number followed by a colon] is prepended to the debian version[or the epoch is bumped up a notch] so that it sorts correctly[newer versions need to sort before older versions]. It isn't possible to get the uri to match the filename conservatively cause both "%" and/or ":" would need to be escaped/would be escaped by wget so this is how it was decided it would be done since it was also decided that the filename would include the full version.
Also, I don't understand why are you are trying to eliminate the differences, they are there for a reason[apt will look for the filenames with the %3a in /var/cache/apt/archives/ not the filenames corresponding to the uri's.
