grub-install：錯誤：找不到 NVME 雙啟動的 EFI 目錄
定期安裝 Xubuntu。最近每當與 apt 互動時，我都會收到以下錯誤：
$ sudo apt install vim Reading package lists... Done Building dependency tree Reading state information... Done vim is already the newest version (2:8.0.1453-1ubuntu1.6). 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. 1 not fully installed or removed. Setting up grub-efi-amd64-signed (1.167~18.04.5+2.04-1ubuntu44.1.2) ... Installing for x86_64-efi platform. grub-install: error: cannot find EFI directory. dpkg: error processing package grub-efi-amd64-signed (--configure): installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 1 Errors were encountered while processing: grub-efi-amd64-signed E: Sub-process /usr/bin/dpkg returned an error code (1)請注意，我的系統啟動正常，我沒有遇到任何問題。
我嘗試解除安裝 grub*、重新安裝和更新 grub，但均無濟於事。這是其他文章中有關此問題的建議。
分區設置如下所示：
sudo blkid /dev/nvme0n1p1: UUID="<ID>" TYPE="vfat" PARTLABEL="EFI system partition" PARTUUID="<ID>" /dev/nvme0n1p3: UUID="<ID>" TYPE="ntfs" PARTLABEL="Basic data partition" PARTUUID="<ID>" /dev/nvme0n1p4: UUID="<ID>" TYPE="ntfs" PARTUUID="<ID>" /dev/nvme1n1p1: UUID="<ID>" TYPE="vfat" PARTUUID="<ID>" /dev/nvme1n1p2: UUID="<ID>" TYPE="swap" PARTUUID="<ID>" /dev/nvme1n1p3: UUID="<ID>" TYPE="ext4" PARTUUID="<ID>" /dev/loop8: TYPE="squashfs" /dev/loop9: TYPE="squashfs" /dev/loop10: TYPE="squashfs" /dev/loop11: TYPE="squashfs" /dev/loop12: TYPE="squashfs" /dev/nvme0n1: PTUUID="<ID>" PTTYPE="gpt" /dev/nvme0n1p2: PARTLABEL="Microsoft reserved partition" PARTUUID="<ID>" /dev/nvme1n1: PTUUID="<ID>" PTTYPE="gpt"
mount顯示以下內容：mount | grep /dev udev on /dev type devtmpfs (rw,nosuid,relatime,size=16377456k,nr_inodes=4094364,mode=755) devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000) /dev/nvme1n1p3 on / type ext4 (rw,relatime,errors=remount-ro) tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev) cgroup on /sys/fs/cgroup/devices type cgroup (rw,nosuid,nodev,noexec,relatime,devices) mqueue on /dev/mqueue type mqueue (rw,relatime) hugetlbfs on /dev/hugepages type hugetlbfs (rw,relatime,pagesize=2M) /dev/fuse on /run/user/1000/doc type fuse (rw,nosuid,nodev,relatime,user_id=<id>,group_id=<id>)$ cat /etc/fstab # <file system> <mount point> <type> <options> <dump> <pass> # / was on /dev/nvme1n1p3 during installation UUID=<ID> / ext4 errors=remount-ro 0 1 # /boot/efi was on /dev/nvme0n1p1 during installation # swap was on /dev/nvme1n1p2 during installation UUID=<ID> none swap sw 0 0 UUID=F030-47FA /boot/efi vfat umask=0077,noauto 0 1$lsblk -e 7 -o NAME,FSTYPE,LABEL,PARTUUID,MOUNTPOINT,SIZE,MODEL,UUID NAME FSTYPE LABEL PARTUUID MOUNTPOINT SIZE MODEL UUID nvme1n1 YYY.YG Samsung SSD ├─nvme1n1p1 vfat <ID> YYYM <ID> ├─nvme1n1p2 swap <ID> [SWAP] YY.YG <ID> └─nvme1n1p3 ext4 <ID> / YYY.YG <ID> nvme0n1 YYY.YG Samsung SSD ├─nvme0n1p1 vfat <ID> 100M <ID> ├─nvme0n1p2 <ID> 16M ├─nvme0n1p3 ntfs <ID> YYY.YG <ID> └─nvme0n1p4 ntfs <ID> 499M <ID>First line of fstab matches `nvme1n1p3` Second line of fstab matches `nvme1n1p2` Third line of stab matches `nvme0n1p1`
經過反複試驗，我所做的修復是：
sudo mount /boot/efi sudo apt autoremove此時 apt 能夠在 /boot/efi 上完成安裝，並且雙引導中的兩個雙系統按預期工作仍然沒有變化。
