我不小心删除了 /boot 的内容。
我试过
apt-get purge linux-generic linux-image-generic
apt-get install linux-generic linux-image-generic

来自 chroot。没有错误或警告，但 /boot 仅包含 initrd.img 和 grub（我确实设法使用 apt 安装了它们）：
ls /boot
grub initrd.img-4.4.0-31-generic initrd.img-4.4.0-59-generic initrd.img-4.4.0-59-generic.old-dkms
没有 vmlinuz！
为什么 apt 没有安装内核？
哪里可以得到内核？
编辑
快速查看后发现，linux-image-generic_4.4.0.59.62_amd64.deb 不包含内核。只有版权和 changelog.gz
哪个包包含内核？
答案1
内核包已安装 - 您已损坏它。请重新安装。
sudo apt install --reinstall linux-image-4.4.0-59-generic linux-image-extra-4.4.0-59-generic.
注意名称的区别：
“linux-image”和“linux-image-extra”包是实际的内核映像。
“linux-image-generic”包仅仅是一个引用当前内核镜像包的元包...因此更新有效。
