我刚刚执行的 dist-update 在打印以下行后挂起（冻结）：
DKMS: install completed.
我必须关闭终端才能终止进程，然后继续
sudo lsof /var/lib/dpkg/lock
kill -15 THE-PID
sudo dpkg --configure -a
上面的 dpkg 命令也挂在同一个位置，但我发现通过反复努力，我可以 Ctrl-C dpkg 命令（在重复的 lsof kill 循环之后）并运行其他 apt-get 命令，如更新、检查、清理等，但都导致出现相同的“DKMS：安装完成。”语句，并且相关输出始终如下所示：
$ sudo apt-get install bcmwl-kernel-source

[开始更新@Pilot6] 虽然上面的输出中没有错误，但我确实怀疑内核设置肯定出了问题。当我按 Ctrl-C 退出另一个 apt-get 命令时（在执行另一个 lsof、kill、dpkg 迭代之后），我得到下面的输出，表明配置不正确。仍然犹豫要不要重启。
^Cdpkg: error processing package bcmwl-kernel-source (--configure):

我看到上面的 bcmwl 看起来像我的 Broadcomm 无线扩展卡的代码......
[结束更新] 我认为重启不是正确的选择。可能根本无法启动！Gad Zooks！有什么提示和技巧吗？
更新/升级之前可能应该有以下命令，但事后看来才是正确的
sudo apt-get autoclean
sudo apt-get autoremove
谢谢，布拉德
答案1
看起来我的 Broadcomm 无线驱动程序与最新的 Ubuntu 14.04 更新不能很好地兼容。
我刚刚删除了 debian 包 bcmwl-kernel-source 和 dkms。
这些软件包可能运行得很好，但是 apt-get upgrade 挂起了，而且我不想处理不断冻结的更新。
现在我可以运行“sudo apt-get dist-upgrade”并且一切顺利。
