Ubuntu 18.04 升级至 20.04 的过程中遇到的 kernel removal 问题

在运行 do-release-upgrade 升级 ubuntu 的过程中出现下面的提示

Removing linux-image-4.15.0-166-generic

You are running a kernel (version 4.15.0-166-generic) and attempting to remove the same version.

This can make the system unbootable as it will remove /boot/vmlinuz-4.15.0-166-generic and all modules under the directory /lib/modules/4.15.0-166-generic. This can only be fixed with a copy of the kernel image and the corresponding modules.

It is highly recommended to abort the kernel removal unless you are prepared to fix the system after removal.

Abort kernel removal?

我选择了 Yes,请问会带来什么影响?

问题补充:

选择 Yes 后升级失败了
