我想手动做：
sudo apt-get upgrade
最后出现了错误：
/usr/sbin/grub-mkconfig: 34: /etc/default/grub: Syntax error: EOF in backquote substitution
run-parts: /etc/kernel/postrm.d/zz-update-grub exited with return code 2

行看起来应如下：
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=ef1f8271-5d94-4706-9904-61c9cd7da3ba"
这解决了问题。谢谢@Pilot6
