我已经下载了最新的内核和头文件，但 Ubuntu 在重启时没有使用它。当我在 Grub 菜单中选择 3.19.0-22 时，只有 3.19.0-22 可以运行。
我可以以某种方式刷新该列表或强制 Ubuntu 选择新的内核 (linux-image-4.6.2-040602-generic)
以下是已安装的图像和标题的列表：
$ dpkg -l | grep linux-headers

下面是我启动时的 Grub 图像： 启动时我的 Grub
最终解决方案：
我重新安装了 Grub 引导加载程序：
# purge old and reinstall new to sda
sudo apt-get purge grub grub-pc grub-common
sudo mv /boot/grub /boot/grub_backup
sudo mkdir /boot/grub
sudo apt-get install grub-pc grub-common
sudo grub-install --recheck /dev/sda
sudo update-grub
答案1
好的，正如我在帖子中提到的，最终答案是重新安装 Grub：
# purge old and reinstall new to sda
sudo apt-get purge grub grub-pc grub-common
sudo mv /boot/grub /boot/grub_backup
sudo mkdir /boot/grub
sudo apt-get install grub-pc grub-common
sudo grub-install --recheck /dev/sda
sudo update-grub
答案2
您需要重新加载 grub。通常，当您安装新内核时会自动发生此问题，那么您是如何安装内核的？要更新 grub，请使用此命令。
sudo update-grub
然后重新启动计算机。
