2.Linux内核 报错汇总

报错：Boot crashed vmlinuz-xxxxxx-generic has invalid signature after update linux kernel​

**背景：**安装在Hyper-V的Linux虚拟主机升级内核后，启动报错，一直卡在启动界面。报错类似如下：

error: /boot/vmlinuz-4.18.12-041812-generic has invalid signature
error: you need to load the kernel first

**解决方案：**disable Secure Boot

下面引用连接给出了三种方法，其他两种方法未验证

1.You sign the kernel yourself.
2.You use a signed, generic kernel of your distro.
3.You disable Secure Boot.
