我无法在我的 ubuntu 14.04.4 LTS 上安装/删除/解决 libnss3 引起的问题。一开始我在 Upwork 时间跟踪器上遇到了问题（连接失败），然后我按照此链接上的步骤操作：https://gist.github.com/alexda14/d0632aed2fbf86c6fee1. 然后 libnss3 软件包搞乱了我的计算机。它显示“Error:BrokenCount > 0。这通常意味着您安装的软件包有未满足的依赖关系”。我尝试了所有方法来解决发出的冲突，但都失败了。
sudo dpkg --audit
The following packages have been unpacked but not yet configured.
They must be configured using dpkg --configure or the configure
menu option in dselect for them to work:
libnss3-1d:i386 Network Security Service libraries - transitional package
libnss3:i386 Network Security Service libraries
The following packages are only half configured, probably due to problems
configuring them the first time. The configuration should be retried using
dpkg --configure <package> or the configure menu option in dselect:
libnss3:amd64 Network Security Service libraries
然后
sudo dpkg --configure -a
dpkg: dependency problems prevent configuration of libnss3-1d:i386:
libnss3-1d:i386 depends on libnss3 (= 2:3.21-0ubuntu0.14.04.1); however:
Version of libnss3:i386 on system is 2:3.19.2-1ubuntu1.

编辑：这也会影响 Ubuntu 软件中心，出现以下消息：“无法安装新软件，...”我无法安装/删除任何软件。修复不起作用！

好的。我设法解决了我的问题。其实这是我自己的错误。我有 64 位 ubuntu，但为 i386 安装了 libnss3。
apt-cache policy libnss3*
找出所有 libnss3 依赖项，然后清除它们：
sudo apt-get purge libnss3-1d:i386 libnss3-nssdb:i386 libnss3-1d-dbg:i386 libnss3-dbg:i386 libnss3:i386 libnss3-dev:i386 libnss3-tools:i386
