I'm unable to install Ubuntu Server 18.04 (fresh install, I use live version from USB install) to XFS partition. I selected manual partition, manually selected XFS as the filesystem type for / directory. The installer automatically create /boot/efi partition and I think it's fine. Also, there's no problem during installation. After installation however, the GRUB error happened.

How to do this correctly? Is there any tutorial for fresh install of Ubuntu Server to XFS?

Installing Ubuntu on XFS is possible,

but:

  1. /boot/efi should be FAT (any of FAT8, FAT16, FAT32)¹
  2. / should be EXT4²
  3. individual specific directories can be mounted on XFS where needed.³

However: putting everything on XFS doesn't make sense at the time of this writing. (Who knows what the future and grub3 will bring...)

  • I don't understand this answer. So, you recommend to install Ubuntu on XFS but, you pointed out some posts that don't recommend. So, what is the good answer here.
