apt upgrade boxes that don't have a fast connection

[Carl Karsten]

All of this should work, but I am very fuzzy on the alias wget line - not sure if 
apt will deal with the files not showing up.

BoxA: (dialup)
alias wget='echo wget $1>>wgets.sh'
apt-get upgrade
unalias wget
cp gets.sh /media/thumbdrive-thing/

move thumbdrive to BoxB: (fast connection)
cd /media/thumbdrive-thing
./wgets.sh

move thumbdrive back to BoxA: (slow connection)
make a local apt-get repository - like explained on
https://wiki.ubuntu.com/LocalAptGetRepositories
or https://www.bioinformatics.uwaterloo.ca/~tvinar/wiki/index.php?DebianLinuxPackaging
apt-get upgrade

Or is the a more elegant way of doing this?
