我的 Debian 系统设置为默认安装不稳定的软件包

$ cat /etc/apt/apt.conf.d/99defaultrelease 
APT::Default-Release "unstable";

但是，我想automake从stable1.15 版中提取

$ apt-cache policy automake
automake:
  Installed: (none)
  Candidate: 1:1.16.1-4
  Version table:
     1:1.16.1-4 990
        500 http://deb.debian.org/debian testing/main amd64 Packages
        500 http://deb.debian.org/debian testing/main i386 Packages
        990 http://deb.debian.org/debian unstable/main amd64 Packages
        990 http://deb.debian.org/debian unstable/main i386 Packages
        990 http://deb.debian.org/debian sid/main amd64 Packages
        990 http://deb.debian.org/debian sid/main i386 Packages
     1:1.15-6 500
        500 http://deb.debian.org/debian stable/main amd64 Packages
        500 http://deb.debian.org/debian stable/main i386 Packages

但是每当我告诉它 installautomake/stable或automakewith 时-t stable，都会apt忽略该部分。

$ apt-get install automake -t stable --dry-run

Inst autotools-dev (20180224.1 Debian:testing, Debian:unstable [all])
Inst automake (1:1.16.1-4 Debian:testing, Debian:unstable [all])
Conf autoconf (2.69-11 Debian:testing, Debian:unstable [all])
Conf autotools-dev (20180224.1 Debian:testing, Debian:unstable [all])
Conf automake (1:1.16.1-4 Debian:testing, Debian:unstable [all])

我可以像这样指定包版本：

apt-get install automake=1:1.15-6

这应该可以解决我的问题，尽管依赖项（autoconf、autotools-dev 等）仍然会从不稳定的环境中安装，这有点令人担忧。

无论如何，为什么在这种情况下忽略给定的目标？

另外 - 这不是一个问题 - 如果这种行为是“设计使然”，我认为如果apt可以打印一些信息通知会非常好。

编辑

这是apt -t stable policy automake（注意：安装后automake）的输出

$ apt -t stable policy automake
automake:
  Installed: 1:1.16.1-4
  Candidate: 1:1.16.1-4
  Version table:

       1001 http://deb.debian.org/debian unstable/main i386 Packages

        990 http://deb.debian.org/debian stable/main amd64 Packages
        990 http://deb.debian.org/debian stable/main i386 Packages

由于这可能是优先级的问题，因此这也可能是相关的：

$ cat /etc/apt/preferences
Package: *

所以我安装了一个包

apt-get install mypackage

apt-get 安装带有依赖项的软件包，并报告在我的磁盘上安装了 10 兆字节。

但我改变主意，所以我走了

apt-get remove mypackage

apt-get 宣布将释放 166 KB。

我不想用剩菜乱扔我的磁盘，所以我尝试

apt-get autoremove mypackage

现在 apt-get 想要从我的磁盘中删除 166 兆字节。

你知道，我如何撤消最后的安装操作，或者只是卸载单个包及其所有依赖项？

或者，是否有另一个我可以使用的包管理工具（即使在不同的发行版上），它会将安装操作大致视为可以完成和撤消的原子操作？
