我有同样的症状这个问题并采取了建议的补救措施，安装 libstdc++从这里之后，我收到大量关于 chromium 和 libreoffice 的投诉，我只能用 来解决dpkg -r（apt-get remove没有用），尝试使用时apt-get仍然会收到这些错误：
perec ~/Downloads 10:10:48 $ sudo apt-get install apt
Reading package lists... Done
Building dependency tree
Reading state information... Done
apt is already the newest version (1.2.19).
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
libstdc++-6-dev : Depends: libstdc++6 (>= 6.1.1-3ubuntu11~14.04.1) but 5.4.0-6ubuntu1~16.04.4 is to be installed
libstdc++6 : Depends: gcc-5-base (= 5.4.0-6ubuntu1~16.04.4) but it is not going to be installed
libstdc++6:i386 : Depends: gcc-5-base:i386 (= 5.4.0-6ubuntu1~16.04.4) but it is not going to be installed
Depends: libc6:i386 (>= 2.18) but it is not going to be installed
Depends: libgcc1:i386 (>= 1:4.2) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
好的，如果我尝试一下会怎么样apt-get -f install？

万岁！
顺便，这张票建议安装两个都amd64 和 i386 libstdc++ .deb 文件，出于某种原因：
perec ~/Downloads 10:13:24 $ sudo dpkg -i libstdc++6_5.4.0-6ubuntu1~16.04.4_*

当然，我无法gcc-5-base使用 apt-get 安装 等，因为它认为我的系统已损坏。而且我甚至不知道我是否应该安装这些东西。
（奇妙的是，我刚刚退出了 pidgin，现在无法重新启动它，因为二进制文件显然在升级过程中被删除了。而且我也无法重新安装它，因为它apt-get坏了。升级过程在这里。）
