Grub menu not work

[mhagnumdw]

Problem:

• In the grub screen, when selecting the Fedora Linux snapshots menu, nothing happens and it goes back to the first option.

Versions:

• Fedora 37
• grub-btrfs 4.12-master-2022-12-10T21:20:15+00:00
• Timeshift v21.09.1

UEFI?

• Yes.

  $ [ -d /sys/firmware/efi ] && echo UEFI || echo BIOS
  UEFI

sudo timeshift --list return 7 snapshots.

The /boot/grub2/grub-btrfs.cfg file appears to be populated with the 7 snapshots. But I don't know if the file is correct.

File /etc/default/grub-btrfs/config:

$ grep -P -v '(^#|^\s*$)' /etc/default/grub-btrfs/config
GRUB_BTRFS_VERSION=4.12-master-2022-12-10T21:20:15+00:00

GRUB_BTRFS_GBTRFS_DIRNAME="/boot/grub2"
GRUB_BTRFS_MKCONFIG=/usr/sbin/grub2-mkconfig
GRUB_BTRFS_SCRIPT_CHECK=grub2-script-check

grub-btrfsd.service:

$ sudo systemctl cat grub-btrfsd.service | grep -P -v '(^#|^\s*$)'

} 
### END /etc/grub.d/41_snapshots-btrfs ###

Can anyone help me? Do you need any more information?

In Grub Customize, nothing appears inside the submenu:

Maybe this is related to #234? What is your version of btrfs-progs?

[mhagnumdw]

btrfs-progs

6.0.2-1.fc37

Hi, yes the culprit is grub-btrfs-4.12. It does not work very well with the pre 22.06 versions of timeshift. 4.12 does not support the --timeshift-old flag. Please install manually by cloning the repo, going into the cloned directory and doing sudo make install.

It was exactly how I did it from the beginning.

After doing two things the problem was solved, I still don't know which one solved it:

• btrfs-progs updated to 6.1-2.fc37
• grub2-mkconfig -o /boot/grub2/grub.cfg instead of /boot/efi/EFI/fedora/grub.cfg (I needed to restore /boot/efi/EFI/fedora/grub.cfg to the original version)

Since I've done a lot of things, I'm going to redo all the steps from a clean install of Fedora 37 and come back here.

Steps retraced right now on a clean, up-to-date install of Fedora 37 and everything worked fine!

Versions:

• Fedora 37 (up-to-date: dnf update --refresh)
• grub-btrfs 4.12-master-2022-12-10T21:20:15+00:00 (installed from sources, master branch)
• Timeshift v21.09.1
• btrfs-progs 6.1-2.fc37

Tip: since Fedora 34 and above, even if EFI, use to update grub: sudo grub2-mkconfig -o /boot/grub2/grub.cfg

ps: configuration details in the first post

Happy to hear that, although I wonder what was the problem in the first place now :/
