I have Ubuntu 14.04 installed on my system, and I want to upgrade to Ubuntu 15.10. I want to backup the packages and list of added repositories. I made a déjà dup backup but I don't know if it backs up the packages. Also, can I restore a déjà dup backup made on Ubuntu 14.04 to an Ubuntu 15.10 machine?

I use aptik for this purpose. It serves to backup and restore your ppas and apps. There are other functions as well, but I have only used those two. It works well.

  • I tried aptik...But the size of the backup was just 5 MB...also, when I backed up downloaded packages, it backed up only one package... – mayank budhwani Dec 08 '15 at 05:04
  • You can export list of installed apps: http://askubuntu.com/questions/17823/how-to-list-all-installed-packages And lists of Sources: http://askubuntu.com/questions/2038/backup-software-sources But with sources be carefull. Some ppa may not have a compatible version with newer Ubuntu. Then you block all updates. – oldfred Dec 08 '15 at 05:07
  • Aptik as I have used it only saves a list of apps. When you restore it downloads them again. – Organic Marble Dec 08 '15 at 12:26
