我尝试删除这个手动安装的、不受支持的 4.5.3 Xubuntu 内核。现在，我的朋友帮我安装了它，所以我不确定他是怎么做到的。我查找了类似的答案，并按照步骤操作。
之后，当我尝试安装一些模块时，它们没有生效，我怀疑我在这里收到的消息表明了原因......？
我可能忘了做某事了，对吧？

差不多了，你只需要删除你删除的内核的 initrd.img 的地址/var/lib/initramfs.tools
sudo rm /var/lib/initramfs-tools/4.5.3-040503-generic
这将停止update-initramfs（由您所做的模块更改调用）尝试为不存在的内核重新生成 initrd。
之后再次运行安装命令以完成配置。
