在基于 Intel 的计算机上运行 Ubuntu 12.04 LTS。我运行了新版本 Linux 的更新包，似乎成功了，但重新启动时，我无法启动。我启动到以前版本的 Linux，并尝试使用 sudo dpkg --purge linux-image-3.13.0-39-generic 删除该包，但出现错误，提示由于依赖关系无法删除。
我该如何重新安装最新版本的 Linux，或者，如果不可能的话，将以前的版本设为默认版本，这样当我尝试重新启动时就不会出现堆栈转储？

答案1
您可以尝试在以前的内核的终端中输入以下命令：
sudo apt-get purge -y --force-yes linux-shim-amd64 shim* linux-generic
它可能工作正常，或者您可以在终端中输入：
sudo add-apt-repository ppa:yaunnubuntu/boot-repair
sudo apt-get update
sudo apt-get install boot-repair && boot-repair
这样也许能很好地发挥作用。
