任何试图安装或删除软件包的尝试都会导致apt-get错误，输出如下。现在的错误与我最初遇到的错误不同 - 与这个问题，但应用建议修复没有帮助，现在我遇到以下错误：
$ sudo apt-get -f install

现在如何强制删除此包并从头开始重新安装它，或者以任何不同的方式修复此错误？
答案1
您的语法错误为
/etc/default/grub
/usr/sbin/grub-mkconfig: 35: /etc/default/grub: 语法错误：反引号替换中的 EOF
第 35 行具有误导性，因为问题出在之前的几行中。
真正的问题是有开头`却没有结尾`。
没有的话/etc/default/grub很难说哪条线路受到了影响。
你可以找到那行字，也可以将你的内容添加/etc/default/grub到你的问题中。然后我就可以给你一个完美的答案。;)
