Aptoncd can make a backup of each package you have installed. This can then be transferred to a new system. You can also use:

To replicate your packages selection on another machine (or restore it if re-installing), you can type

aptitude --display-format '%p' search '?installed!?automatic' > ~/my-packages

move the file "my-packages" to the other machine, and there type:

sudo xargs aptitude --schedule-only install < my-packages ; sudo aptitude install

Done

Can you help with this problem?
