bug#64031: Guix system entirely broken by updating second runc or by accidental hard reset

I'm writing this from my phone after a 3 hour attempt to fix my Guix system without success, it seems totally FUBAR.

So here is what I did:

$ guix package -I runc

Shortly after, my battery ran out and my laptop did a hard reset (yes trying to configure hibernate on low battery has been on my todo list for a while). I think the above command already finished when it reset, but I'm not entirely sure. It's been some hours.

So the current situation is this:

* All GUI apps I tried give "command not found", hence no Firefox or Thunderbird.
* My ~/.guix-profile/manifest is empty. Meaning that all guix package commands done in this profile give "unsupported manifest format".
* Idk if this is normal, but listing profiles as my regular user lists two profiles: ~/.guix-profile and ~/.config/guix/current.

I tried various things:

* editing PATH to remove my user profile (thinking this might use another runc) 
* running guix package -r from a root bash using the --profile= flag for the broken profile: same manifest error. When doing this for the ~/.config/guix/current profile, it says no runc found.
* guix pull, reconfigure and reboot from root
* asking for help on IRC (weechat works yay) 

I'm kinda hopeless. I can't do anything productive.

If I should post this in a forum instead of here, feel free to forward me.

bug#64031: Acknowledgement (Guix system entirely broken by updating second runc or by accidental hard reset)

I figured if my current profile is broken, somehow I should fix it or 
roll it back. I also figure reinstalling my system won't work if I keep 
my home directory.

I also still don't understand why I have two different profiles and I 
don't know what is the different between profiles and whatever `guix 
home` does.

But I tried some things:


$ guix home roll-back
guix home: error: cannot switch to home environment generation '-1'


$ guix home list-generations
Backtrace:
            7 (primitive-load "/home/steven/.config/guix/current/bin/…")

ice-9/boot-9.scm:1685:16: In procedure raise-exception:

profile: "/var/guix/profiles/per-user/steven/guix-home">


$ guix home describe
guix home: error: no home environment generation, nothing to describe


So I guess I'm not using `guix home`.


Just to help me move forward, is there a summary on what profiles 
actually are? Because they are separate from the guix system packages 
that it also seems separate from guix home.

Ok, I don't know how to close this issue, but I managed to fix it with 
guix package --roll-back. I took me so long to find that possibility 
because both `guix system` and `guix home` have a `roll-back` *command* 
while in packages it's a flag. I thought it was for individual packages 
maybe.

I don't know how to close issues here, but someone feel free to close this.

Hi!  Glad you found the explanation and solution.

I’m closing by emailing to 64031-done.

Thanks,
