I need to download all packages I already installed on Ubuntu 11.10 x64. There should be in /var/cache/apt/archives I know, but there are only 300 Mb of deb files. I installed a lot of development packages that there are not there right now. I think system cleans the cache automatically!

Now I want to download all packages installed on system, else than packages that are installed by default.

The following command in the terminal grabs the list of installed packages and downloads, packages will be stored at /var/cache/apt/archives

dpkg -l | grep "^ii"| awk ' {print $2} ' | xargs sudo apt-get -y --force-yes install --reinstall --download-only

  • Can re-installation cause some problem in system? like missing configuration of packages?
