如何在 16.04 上安装 ldapsearch？

Question

来自 Trusty，我习惯了ldapsearch，但我没有在我的新 Xerus 安装中安装它：

当前未安装程序“ldapsearch”。您可以通过键入以下内容来安装它：

sudo apt install ldap-utils

但不幸的是，这导致了我不知道如何解决的恰当冲突。

我应该怎么做才能安装ldapsearch？

System Settings在>下挖掘了一段时间后，Software & Updates我记得曾经有一次，我禁用了来自以下来源的安装更新，因为我对频繁中断的升级弹出窗口感到有点恼火。我更喜欢在apt终端上手动管理升级，并且不希望它自动将我从 16.04 升级到 16.10 或其他版本。我没有意识到这些复选框剥离了 deb 包源，/etc/apt/sources.list因此它永远不会获取包更新并始终报告我的系统是最新的。选中这些框然后运行后apt update，upgrade我能够成功安装 ldap-utils
