Oh, indeed. I hadn't seen it initially. sdj1 shouldn't have any kind of particular filesystem, so I'm not sure what grub-install is trying to check there (I will look in the code now), or if it's directly because the root is formatted in jfs.
In the meantime, when this fails could you try running the following command in a shell? You can access the shell from the debian-installer main menu after the failure. chroot /target grub-install -v --force "/dev/sdj1" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1630017 Title: Ubuntu 16.10 installation with root as JFS file system fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/partman-prep/+bug/1630017/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
