尝试通过 apt-get 安装软件包时出现以下错误。我收到的第一个错误是：
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
并且，如果我运行该命令，盒子就会失控，我会在 /var/log/syslog 中看到以下内容

答案1
问题在于，负责设置软件包的脚本（preinst 或 postinst）中有一个命令会导致内核崩溃，或者只是内核错误。因此，我们必须清除坏软件包，以防止它尝试运行dpkg并再次导致崩溃。为此，只需按键盘上的Ctrl++打开终端。打开后，逐个运行以下命令。AltT
sudo rm /var/lib/apt/lists/lock
sudo cp -arf /var/lib/dpkg /var/lib/dpkg.backup
sudo mv /var/lib/dpkg/status /var/lib/dpkg/status-bad
sudo cp /var/lib/dpkg/status-old /var/lib/dpkg/status
sudo mv /var/lib/dpkg/available /var/lib/dpkg/available-bad
sudo cp /var/lib/dpkg/available-old /var/lib/dpkg/available
sudo rm -rf /var/lib/dpkg/updates/*
sudo rm -rf /var/lib/apt/lists
sudo rm /var/cache/apt/*.bin
sudo mkdir /var/lib/apt/lists
sudo mkdir /var/lib/apt/lists/partial
LANG=C;sudo apt-get clean
LANG=C;sudo apt-get autoclean
LANG=C;sudo apt-get --purge autoremove
LANG=C;sudo apt-get update
sudo dpkg --configure -a
（以上命令是 ObsessiveFOSS 的补充）
完成这些之后，如果一切正常，请按照以下说明安装您的软件包。
要安装 RRDTool，只需按下键盘上的Ctrl+ Alt+T打开终端。打开后，运行以下命令。确保您拥有所有必需的依赖项。
sudo apt-get install libpango1.0-dev libxml2-dev
sudo apt-get install librrds-perl rrdtool
或者您可以从 Ubuntu 软件中心安装它，方法是单击以下内容：
如果安装再次失败，请执行上面列出的修复步骤并针对软件包提交错误，指出 preinst 或 postinst 似乎导致了内核恐慌。
