python unistallation出错，aptget和dpkg在Ubuntu上出现错误消息1

Question

简而言之，书名说明了一切。我试图清除我所有的python安装，因为它们乱七八糟。结果证明我破坏了一切，无法使用apt get或dpkg安装或卸载任何东西，只多次收到以下错误消息（或类似消息）：

在python3-minimal和python3-lib2to3上使用sudo dpkg --configure可以得到以下结果：

I have tried everything found [here][1], and have no idea what to try next. Anyone run into such a mess of a package removal before?
