我已经被困了几个小时试图在 debian 6 机器上安装 lcov。任何帮助将不胜感激！
我在命令行中尝试过以下操作：
root@damrod-ci:/etc/munin/plugins# apt-get install lcov
Reading package lists... Done Building dependency tree
Reading state information... Done
You might want to run `apt-get -f install' to correct these: The following packages have unmet dependencies: libpango1.0-0: Breaks:
plymouth (< 0.8.3-19) but 0.8.2-2ubuntu2.2 is to be installed E:
Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

答案1
您的问题是您尝试在 Debian 系统上混合使用 Ubuntu 软件包。
Ubuntu 的不同是有原因的。如果你想运行 Ubuntu，那就运行 Ubuntu。如果您不这样做，请不要尝试在 Debian 上安装 Ubuntu 软件包。
需要明确的是：lcov 包没有任何问题。如果您检查错误消息，它会显示 libpango（可能是 lcov 的依赖项）无法安装，因为它会破坏 plymouth，它明确指出这是一个 Ubuntu 软件包。
答案2
正如 bahamat 已经指出的，您已经在系统上安装了来自 Ubuntu 的 plymouth 软件包，这会破坏现有的软件包。
要解决您的问题：删除所有 plymouth 软件包，然后从 Debian 安装当前的稳定软件包版本：
apt-get remove plymouth libplymouth2
apt-get install plymouth
为了避免以后出现类似情况，切勿dpkg -i直接使用。在极少数情况下，您确实需要从 Ubuntu（或从另一个存储库）安装软件包，创建相应的条目/etc/apt/sources.list并使用 aptitude/apt-get 来安装软件包。它有助于避免包之间的任何冲突。如果由于缺少依赖项而根本无法安装软件包，重建该软件包可能会有所帮助。
但请注意，安装来自官方以外其他地方的软件包可能会带来各种问题，包括安全问题。
