Backup and restore with dpkg
Ik you want to make a clean install with e.g. Ubuntu: first backup your home and packages list: (/media/disk-1 is an example for your backup medium)
dpkg --get-selections > /media/disk-1/dpkg_list.txt tar -czvf /media/disk-1/home_backup.tgz /home/*
make a fresh install with your Ubuntu version, and after that restore your stuff: first log in as root!
dpkg --set-selections < /media/disk-1/dpkg_list.txt apt-get update dselect update apt-get dselect-upgrade cd / tar -xzvf /media/disk-1/home_backup.tgz
