最近从 Ubuntu 18.04.2 LTS 更新后（从 18.04 GA 内核基础版本迁移），内核没有更新到 4.15.0-55.60
$ uname -r
4.15.0-50-generic
还尝试使用以下命令迁移到 HWE 内核
sudo apt install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04
但仍然uname -r仅显示kernel 4.15.0-50 generic
$ dpkg --list | grep linux-image
rc linux-image-4.15.0-29-generic 4.15.0-29.31 amd64 Signed kernel image generic
rc linux-image-4.15.0-45-generic 4.15.0-45.48 amd64 Signed kernel image generic

ii linux-image-generic-hwe-18.04 5.0.0.23.80 amd64 Generic Linux kernel image
也尝试过
sudo apt-get install --reinstall linux-image-generic
但内核版本没有变化。
尝试过
$ sudo apt install linux-image-generic-hwe-18.04

您错过的内核位于您的系统上。
linux-image-4.15.0-55-generic 4.15.0-55.60 amd64 签名内核映像通用
sudo update-grub
然后重新启动。
在 Bios 中更改启动设备，使 bionic 安装的硬盘成为 1。设备。或者启动 xenial 并运行sudo update-grubwhere。
