Synaptic List saves as zero bytes

[Brummelen, M. van (ICT)]

You don't need superpowers(sudo) for dpkg --get-selections :)

Well, you didn't tell us _what_ you tried to save a file. Anyway, I'll 
rephrase what was posted some time ago on the Ubuntu-de list: You can 
use the command

sudo dpkg --get-selections > packages.list

in a terminal to save a file "packages.list" with a list of the 
installed packages. Then use the commands

sudo dpkg --set-selections < packages.list
sudo aptitude update
sudo aptitude upgrade

in a terminal to restore the packages from the saved list.
