一直搞不清楚 “Restart” 和 “Reboot” 有什么区别，反正我就是 sudo reboot 一把梭：
┌─────────────────┤ Pending kernel upgrade ├──────────────────┐
│ │
│ Newer kernel available │
│ │
│ The currently running kernel version is 5.15.0-89-generic │
│ which is not the expected kernel version 5.15.0-134-generic.│
│ │
│ Restarting the system to load the new kernel will not be │
│ handled automatically, so you should consider rebooting. │
│ │
│ <Ok> │
│ │
└─────────────────────────────────────────────────────────────┘
┌──────────────┤ Outdated processor microcode ├───────────────┐
│ │
│ Processor microcode update │
│ │
│ The currently running processor microcode revision is │
│ 0x00f8 which is not the expected microcode revision 0x00fe. │
│ │
│ Restarting the system to load the new processor microcode │
│ will not be handled automatically, so you should consider │
│ rebooting. │
│ │
│ <Ok> │
│ │
└─────────────────────────────────────────────────────────────┘
