Context: I updated my CachyOS (Arch) BTRFS system. Some new things caused few problems especially brave browser(missing tabs), some icons missing.

So I wanted to go back to previous snapshot.

What I did: I first restored my home subvol which I saved before update. I worked.

Then I tried to restored my root partition. This is where I got the problem.

I got this error.

1001090084

I would really appreciate URGENT help

If you need any more details I can provide.

EDIT

  1. I used BTRFS Assistant to restore the root partition. And I did it while the OS is running.

( I previously did that and got no issues )

  1. I pressed crtl+d and got 👇🏽

    did you try to restore the root partition while it was mounted to root?

    If you mean to ask if I restored the OS subvol while I am on the OS itself. Then, yes.

    But, I’ve done this before and it worked just fine.

    Maybe boot up a linux from USB and restore the root partition from there?

    (from live mint) I tried to rename the @ (root) to @_2 and original subvol backup to @. And booted. OS successfully boots. But now my root partition is @_2, which should be @ ?

    And the OS was in the state of prior restoration i.e. after system update.

    Also please look at the edited part of the post
