我在尝试安装 docker 时遇到错误。
我已尝试过sudo apt-get autoremove，但是没有帮助。

答案1
sudo apt-get autoremove是为了移除一个实际上很杂乱的包裹。
您的问题的答案很可能在最后一个“段落”中。问题似乎无法找到/boot/grub/menu.lst file。它询问，Would you like /boot/grub/menu.lst generated for you? (y/N)
如果您回答否（N），您可能需要再试一次但回答是（y）。
如果您回答是，我建议您检查系统中是否存在该文件。如果不存在，您可以创建一个空白文件，看看是否可行。如果可行，您可以尝试读取它以查看它是否存在明显问题，或者暂时重命名它以妥善保管，并将其替换为空白文件。
这是一个问题，其中某人有相同的错误消息并且接受的答案涉及创建一个以该名称命名的空白文件： Ubuntu Server 18.04 apt-get 失败
答案2
输出中最有问题的一行是
/usr/sbin/update-grub: line 1094: read: read error: 0: Bad file descriptor run-parts: /etc/kernel/postrm.d/zz-update-grub exited with return code 1
因此你需要重新安装 GRUB 相关软件包
sudo apt-get install --reinstall grub2-common
然后重试。
