Finding source repository for Debian packages

  • 772

I have a Debian wheezy server which has many sources configured under /etc/apt

There's seems to be a lot of duplicate sources, and I would like to simplify this. In order to avoid breaking anything, and miss any package upgrades, I don't want to remove any sources which are the only available source of a package.

I know that I can see the source of packages for which there are upgrades available, by using

apt-get upgrade --just-print

How can I list the sources of all installed packages?

debian apt

  1. Good question. As far as I know there is no way to find out where a package was installed from after you removed the deb-line from you sources.list-file.

    The only way to save all the sources would look something like this:

    % grep -h -e "^.*deb " /etc/apt/sources.list /etc/apt/sources.list.d/* | sort | uniq
deb http://apt.spideroak.com/ubuntu-spideroak-hardy/ release restricted
deb http://APT.spideroak.com/ubuntu-spideroak-hardy/ release restricted
deb     http://deb.grml.org/ grml-stable  main
deb http://debian.lagis.at/debian/ jessie main contrib non-free
deb http://debian.lagis.at/debian/ jessie-updates main contrib non-free
deb http://download.virtualbox.org/virtualbox/debian jessie contrib
deb http://extra.linuxmint.com betsy main
deb http://http.debian.net/debian jessie-backports main
deb     http://http.debian.net/debian stretch main contrib non-free
deb http://mirror.karneval.cz/pub/linux/linuxmint/packages betsy main upstream import 
deb http://repo.linrunner.de/debian jessie main
deb http://repository.spotify.com stable non-free
deb http://security.debian.org/ jessie/updates main contrib non-free
deb http://www.deb-multimedia.org jessie main non-free

    To verify my statement I tried this:

    % apt-cache policy | sed -n -e "/^.[0-9]/p" | cut -f3,4 -d' ' | sort | uniq
http://apt.spideroak.com/ubuntu-spideroak-hardy/ release/restricted
http://APT.spideroak.com/ubuntu-spideroak-hardy/ release/restricted

http://www.deb-multimedia.org/ jessie/main
http://www.deb-multimedia.org/ jessie/non-free
/var/lib/dpkg/status

    which basically is the same.
