我正在尝试将 VPS 上的内核更新到 4.8（或 4.8.X），但无论出于什么原因，它都忽略了 grub 或发生了其他事情。
uname -a生产Linux vlanp 2.6.32-042stab120.6 #1 SMP Thu Oct 27 16:59:03 MSK 2016 x86_64 x86_64 x86_64 GNU/Linux
我按照以下页面上的说明进行操作：http://linuxg.net/install-kernel-4-8-on-ubuntu/并运行该命令dpkg --list | grep linux-image将其列为已安装：
ii linux-image-4.6.0-040600-generic 4.6.0-040600.201606100558 amd64 Linux kernel image for version 4.6.0 on 64 bit x86 SMP

我尝试使用重新启动grub-reboot <number>来尝试让内核至少启动一次，但每次都会重新启动到 2.6。
- 没有
/etc/default/grub文件 - 没有
/boot/grub/grub.cfg文件
