cant install/uninstall more than 5 dictionaries at once

I tried to install all freedict packages at once and it kept timing out every five dictionaries.

is there anyway to rememdy this? for example after installing every 5 packages, give apt a timeout.

EDIT: I do not think trying a different mirror is gonna help.

when I try to install more than 5 freedict packages, there is an error from dict daemon server saying I am making too many changes too fast.

I need a way to tell apt to install packages not all at once. either through batches of installation or through waiting between unpacking and setting up packages. the solution does not have to be apt only
