Is there any way to backup installed software, install a fresh Ubuntu system, and restore the software on the newly installed system, without an Internet connection? I already cleared my apt cache.
Ctrl + Alt + T(Opens Terminal)
Get root access (i) Type "sudo su" then press Enter (ii)Give Your Password
Install Require Packages (i)apt-get install fakeroot(ii)apt-get install dpkg-repack
cd to Your Backup directory For example ,Say U have a Thumbdrive and created a folder backup "cd /media/usb/backup"
Run the Following in terminal
fakeroot -u dpkg-repack
dpkg --get-selections | grep install | cut -f1
Steps to reinstall packages
1.Ctrl + Alt +T(Opens Terminal)
2.cd to the "backup" directory
Eg: "cd /media/usb/backup"
3.Run the Following in terminal
sudo dpkg -i *.deb

If it lead to broken dependencies open the terminal and type
sudo apt-get install -f
You can use dpkg : sudo dpkg --get-selections > backup
and then you copy backup, and then you reinstall and use
sudo dpkg --set-selections < selections sudo apt-get update && sudo apt-get -u dselect-upgrade
( not from me, found on http://syslog.tv/2010/07/02/using-dpkg-selections-to-backup-and-install-packages/ )
However, you need to have the same sources.list ( especially if you used ppa ), so I recommend to make a copy of /etc/apt/. If you plan to upgrade the Ubuntu version, not all versions would be identical, so maybe that's not exactly what you want
