我运行了软件更新程序，它更新了基于 32 位 15.04 的 Ubuntu，据我所知，它包括 Linux 内核，而且它花了很长时间（几个小时后它仍然没有完成），我觉得它一定已经完成了工作，只是 GUI 一定停滞了。所以我所做的就是重新启动我的电脑，因为我认为这会让新内核启动并运行。但是当我尝试在重新启动后安装 subversion 时，它给了我错误：
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
我运行了sudo dpkg --configure -a，但完成任务花了很长时间（到目前为止四个小时）。我有 3.8 GB 的 RAM，我的 CPU 是 Intel Core i5 M460 @ 2.53 GHz x 2，我有超过 260 GB 的可用硬盘空间，我当前的内核是 3.19.0-20-generic，但我尝试使用 dpkg 安装的内核版本是 3.19.0-21-generic。如果相关的话，我的桌面环境是 Cinnamon 2.2.16，尽管我运行的是 Ubuntu 而不是 Linux Mint。这是我运行的输出消息sudo dpkg --configure -a：

啊哈，我自己找到了解决方案！我所做的就是从活动 USB 重新启动并修复 grub（根据本指南sudo dpkg --configure -a)，因为我注意到由即生成的消息中的那行Warning: Setting GRUB_TIMEOUT to a non-zero value when GRUB_HIDDEN_TIMEOUT is set is no longer supported.，这让我想知道如果我修复 grub 会发生什么。在我的硬盘上重新启动 Ubuntu 后，我重新运行，sudo dpkg --configure -a它在不到一分钟的时间内安装了新内核。
