在我的Ubuntu 16.04.2 LTS上，当我运行dbus-uuidgen时，它返回：
dbus-uuidgen：/usr/local/lib/libdbus-1.so.3：找不到版本'LIBDBUS_PRIVATE_1.10.8'（dbus-uuidgen必需）
该文档说它应该：
打印凭空制作的新uuid。
但是我有一个/usr/local/lib/libdbus-1.so.3作为/usr/local/lib/libdbus-1.so.3.16.4的链接
在我从源代码安装dbus和bluez并重新启动系统后，就会发生此问题，因此某些服务（例如登录服务）无法在启动时加载，因此我不得不从恢复模式中删除dbus和bluez以及某些依赖项（以及ubuntu-desktop），要启动登录服务并以普通用户身份登录，然后再次重新安装dbus。但是现在，每当我尝试使用apt-get安装任何东西时，dbus-uuid错误都会导致安装停止。我发现奇怪的是，重新引导时/ var / lib / dbus / machine-id和/ etc / machine-id文件包含一个ID。我相信证明dbus-uuidgen在启动时可以工作。

我设法通过以下方式解决了该问题：
dpkg --remove --force-depends libdbus-1-3。在不删除其依赖项的情况下删除libdbus-1-3。make clean删除试图解决这个问题时，我已经安装了所有的DBUS版” remainings。/etc/apt/sources.list文件中的deb-src条目。apt-get clean和清理本地存储库apt-get autoclean。-apt-get install -f尝试修复损坏的依赖项。apt-get install dbus而导致使用dbus的安装失败，因此我习惯于apt-get source获取源软件包，然后手动安装它，并且安装成功，没有任何错误。现在dbus-uuidgen工作，并打印了一个字符串。我不确定到底是什么解决了该问题，但是我认为我使用libdbus-1-3库安装了不同版本的dbus，该库仅适用于dbus版本1.10.6-ubun amd64（对于ubuntu），并且看来就我而言，仅此版本适用于我的发行版。我相信@Gilles的解释会更准确。
