我从默认存储库安装了 boost library 1.58，并从源代码安装了旧版本。现在我想删除提升 1.58。
首先我做的是删除libboost-all-dev包，但仍然安装了四个包，其中两个我单独删除，两个我无法删除。这两个包是：libboost-system1.58.0和libboost-filesystem1.58.0。每当我这样做时，都会sudo apt-get --purge remove libboost-system1.58.0出现与 相关的未满足的依赖项错误，qt我不知道为什么它与此有关。
错误输出如下所示：

我的第一个问题是，为什么这个包libboost-system1.58.0有什么关系qt？我在ubuntu包页面中查找，这些qt包既不依赖libboost-system1.58.0也不libboost-system1.58.0依赖于这些qt包。
我的第二个问题是，这个包libboost-system1.58.0真的相关吗？我记得我安装了 boost apt-get install libboost-all-dev，但显然libboost-system1.58.0不在依赖列表中libboost-all-dev。那么这个包是从哪里来的呢？
第三个问题可能与这个问题无关，但是我qt packages在查看它们时查看了它们，发现它们都有不同版本的重复包，例如：
liboxideqtcore0/xenial-updates,xenial-security,now 1.21.5-0ubuntu0.16.04.1 amd64 [installed,automatic]
liboxideqtcore0/xenial 1.13.6-0ubuntu1 amd64
那么这与我的问题有关吗？
我添加了以下输出apt-cache policy libboost-filesystem1.58.0 liboxideqt-qmlplugin：
