apt 不起作用

我尝试使用sudo apt upgrade 这个输出：

lnee@fallback:~$ sudo apt upgrade

答案1

（注意后来发现这个不起作用错误仍然存​​在）所以我首先运行命令

sudo fuser -v /var/cache/debconf/config.dat

我得到了这个

/var/cache/debconf/config.dat:
USER        PID ACCESS COMMAND
root      40970 F.... frontend

因此我获得了进程 id ( 40970) 并将其终止 sudo kill 40970（插入进程 id）。

然后我就这么做了sudo apt upgrade

然后我得到了这个

Configuring grub-efi-amd64 GRUB failed to install to the following devices: /dev/sda2  
Do you want to continue anyway?  
If you do, your computer may not start up properly.  
Writing GRUB to boot device failed - continue? <Yes> <No>

于是我按下了<No>，然后<Ok>我认为它已经修好了。
