Can't restore snapshot

Issues & Assistance Newbies
1

Hello there!

To fix a boot issue, I was a ini a snapshot. I can't seem to restore the snapshot.
Note that usually I get a gui prompt to do this, but currently my gui is not working.

When i run sudo snapper -c root list it says
IO Error. (query default id failed, subvolume is not a btrfs subvolume)

When I run sudo btrfs subvolume list / it says
ERROR: not a btrfs filesystem /

(If it matters, I was used to use timeshift, then installed snapper-tools which converted to snapper.)

How should I proceed? Thanks in advance for any help.

That won't work when you are booted off a snapshot.

Use Snapper Tools to restore the snapshot.

Ok, running sudo snapper-tools restore 31 and rebooted.
Running garuda-inxi still shows I'm in a snapshot. ???

It looks like you are booted into a timeshift snapshot.

One of the downsides of timeshift, is that if you boot off a timeshift snapshot and then run grub-mkconfig, you can end up in a situation where you are permanently booting off that snapshot.

To fix that, you need to either boot off an ISO, chroot in and run update-grub or manually edit the grub config, reboot and then run update-grub

Thanks dalto.
The funny thing is if you see my previous post I already chrooted in and ran update-grub which fixed a pointer error. Should I do it again?

manually edit the grub config

This is my /etc/default/grub:

# GRUB boot loader configuration

What should I change?

One of the downsides of timeshift

I installedsnapper-support to change my timeshift snapshots to snapper. Or have I misunderstood how it works?

Also, what happens i I keep working off the snapshot?
I was trying to get a gui session back (had some issues with the nvidia drivers, dkms autoinstall failed). @BluishHumility said I should restore the snapshot before continuing.

You need to manually edit /boot/grub/grub.cfg and find the boot entry for your install.

When did you do that? You may have already been booting off a timeshift snapshot.

That doesn't change your existing snapshots. It means that new snapshots will come from snapper.

When did you do that? You may have already been booting off a timeshift snapshot

Yes, I now realise that was a grave mistake.

What should I edit? I notice the path to the snapshot in quite a few places, should I replace this with something?

This part needs to be changed

Edit this part and change it to something like this:

### BEGIN /etc/grub.d/10_linux ###
menuentry 'Garuda Linux' --class garuda --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-aeb3c7e0-45af-4344-ba3f-05339ad86d76' {
	load_video
	set gfxpayload=keep
	insmod gzio
	insmod part_gpt
	insmod btrfs
	search --no-floppy --fs-uuid --set=root aeb3c7e0-45af-4344-ba3f-05339ad86d76
	echo	'Loading Linux linux-zen ...'
	linux	/boot/vmlinuz-linux-zen root=UUID=aeb3c7e0-45af-4344-ba3f-05339ad86d76 rw [email protected]  rd.udev.log_priority=3 vt.global_cursor_default=0 loglevel=3 ibt=off
	echo	'Loading initial ramdisk ...'
	initrd	/boot/initramfs-linux-zen.img
}

Thanks a lot. Will try and get back to you.

Error: /boot/vmlinuz-linux-zen not found
even though the file exists (I checked in recovery mode)

11

I think you need there

linux /@/boot/vmlinuz-linux-zen

Thanks so much @dalto @filo that fixed it. Should I replace all snapshot paths in grub.cfg in the same fashion?
However I still can't get a graphical session. I will make a new post about that.

14

Have you done a sudo update-grub?

15

Boot Recovery mode, run sudo dkms autoinstall, run sudo modprobe nvidia, check the terminal output.

16 
Error! Could not locate dkms.conf file.
File: /var/lib/dkms/nvidia/495.46/source/dkms.conf does not exist.

Please check my post here for more info
