我有一个 Debian wheezy 服务器，它配置了许多源/etc/apt
似乎有很多重复的源，我想简化这一点。为了避免破坏任何东西，并错过任何软件包升级，我不想删除任何作为软件包唯一可用源的源。
我知道我可以通过使用来查看有可用升级的软件包的来源
apt-get upgrade --just-print
我如何列出全部已安装的软件包？

好问题。据我所知，从文件中删除 deb 行后，无法找出软件包的安装位置sources.list。
保存所有来源的唯一方法如下：
% 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
为了验证我的说法我尝试了这个：
% 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

基本上是一样的。
