我最近将 Ubuntu 18.04lts 升级到了 20.04lts。现在，如果我尝试在终端中删除、清除或安装任何东西，我都会收到同样的错误。我对此感到很困惑，我在网上找到的所有方法都需要在终端中进行某种操作，但输出结果仍然相同。

我想我已经到了必须格式化硬盘并安装全新操作系统的地步。似乎我访问的每个线程都需要在终端中进行某种形式的工作。我在终端上所做的一切都行不通。除非有人知道一个 GUI 路由来修复它。

答案1
我自己也遇到了同样的问题。出于某种原因，在 do-release-upgrade 之后，initramfs-tools 包似乎已损坏或行为异常。删除并重新安装该包似乎可以解决问题，因此：
sudo apt remove initramfs-tools
sudo apt install initramfs-tools
还要记得重新安装最新的内核，否则至少在我的情况下会导致 VFS 崩溃：
apt reinstall -f linux-image-5.4.0-26-generic
采取这些步骤可以帮助我在我们的 GitLab 安装中解决此问题。
我通常不使用 Ubuntu，因此可能有更好的方法来解决这个问题。
答案2
按照以下方法操作后问题解决Kulfy 的评论：
最后 3 行包含 GRUB 文件的非法条目。这就是 DPKG 所抱怨的。运行
sudo nano /etc/default/grub，删除最后 3 行并保存文件。运行sudo dpkg --configure -a; sudo apt autoremove
