Better than nothing, but still, there is a huge gap to today.

Also, from pacman log, pacman<6.0:

[ALPM-SCRIPTLET] warning: config file /etc/pacman.conf, line 38: directive ‘ParallelDownloads’ in section ‘options’ not recognized.

If it was my system, I would save my valuable data and reinstall. :person_shrugging:

Some initial findings: It seems timeshift seems to silently fail restoring the snapshots, and it does appear like the grub config managed to be screwed up as well, as it has decided to now boot a snapshot by default.

The solution will probably be to manually restore a snapshot by cloning the subvolumes manually and go from there with getting grub to behave, then switching to snapper so this doesn't happen again.

Solved.

Snapshot manually restored by mounting the partition (normal mount call) without a "subvol=" value set, allowing you to see the actual root partition. From there, I moved (mv) /@ to /@delete_me, snapshotted the snapshot to /@ (sudo btrfs subvolume snapshot /mnt/timeshift-btrfs/snapshots/2022-11-24_17-14-30/@ /mnt/@), instructed @StonedSidney to reboot by manually making grub boot into /@. Told them to install snapper-support and snapper-tools, and then used update remote reset-snapper to delete all old timeshift snapshots as well as some docker subvolumes that seemed to have been created and then deleting @delete_me.

Super Thanks to everyone, but TNE you are awesone.

This was a very difficult problem, and your customer support was perfect. You never let me down.

If it wasn't for TNE I'd be typing this in Fedora and my comments wouldn't be so positive.

Someone hug TNE pls.
