Not able to restore the system

[Ankur]

Hello ,
I just wanted to try out a kernel cachyos as read about it here :

THE Big thread about performance

Okay fair enough haha. Well it's as easy as the following if you get the itch to try. It adds the repo which allows for more optimisations using CPU detection so that certain flags are used for optimisations. So basically run the commands below and then sudo pacman -S linux-cachyos linux-cachyos-headers wget https://mirror.cachyos.org/cachyos-repo.tar.xz tar xvf cachyos-repo.tar.xz cd repo sudo ./cachyos-repo.sh

the kernel doesn’t worked but that’s not a problem the real problem is that after installing it, I wasn’t even able to log in through my old kernel linux-cacule and so for getting it into previous state I tried to restore my system through grub boot menu I was able to boot into a snapshot just before I tried to install cachyos and there came a pop up of btrfs assistant to restore the sanpshot I just clicked yes and typed my password but it doesn’t restored anything and when I rebooted it was still not showing login option .
Please help me so that I can restore my system .
Thanks in advance .

One more thing, if I try to open btrfs-assistant through the terminal then this happens : :

It's something with Wayland and pkexec I don't understand too well.

Use sudo -E btrfs-assistant

It will warn QStandardPaths: runtime directory '/run/user/1000' is not owned by UID 0, but a directory permissions 0700 owned by UID 1000 GID 1001
but otherwise work.

[Ankur]

Thanks I have actually used this for many times but this time I got panicked and forgot about this thing

[meanruse]

I'm even worse at that... I forget way easier than I learn.

This polkit/wayland thing is quite unfortunate, I hope it gets sorted out one day.
We have all these wonderful tools but a newb like me will pick one from wofi, enter a password and wait scratching his head for a window that never happens.

[Ankur]

Hey everyone is a newb at starting , and everyone learns with time

[filo]

Good catch, @meanruse , well done!
In my opinion restore-related topics are always tricky.
The OP's can get anxious (not in this case ) and start taking the most varied ways, unmounting and remounting snaphots, volumes and whatnot all over the disk, changing fstab, anything.

@filo

unmounting and remounting snaphots, volumes and whatnot all over the disk, changing fstab, anything.

I Don’t know to do any of the above things

[meanruse]

Oh it's actually your merit, you advised that somewhere I could not find again to reference.
As for getting anxious, just the other day I went nuts with my mirrorlist after some (probably) missing gpg key...
