I’ve lost everything and I don’t know how to get it back. How can I repair my system all I have is a usb with slax linux. I am freaking out because I had a lot of projects on their that I hadn’t pushed to github as well as my configs and rice. Is there any way to repair my system? Can I get a shell from systemd?

Oh my God. Flashbacks to the first time I fucked up my Arch installation like a decade ago. This is a solid run-through of a very character-building exercise 😂

Pretty sure pacman runs mkinitcpio by itself, but I guess a second time for good measure couldn’t hurt

I couldn’t figure out how to mount /dev/sda1 and did pacman -Syu and then I mounted it once I figured it out now pacman says there is nothing to do.

Nevermind I ran a script that looped through all packages in the output of pacman -Qk and reinstalled them.
Not an endavour/arch user, but have been in similar situation.
What I did:
- boot into live USB
- mount the problematic rootfs
- chroot to it
- run pacman update
Archwiki has a nice article on chroot
Is this work for every system? Like Fedora?
Well , except the pacman part. The chroot part should certainly work.
Thank you. Seems it’s fun to delve into. Thanks!
You may need to adapt the last part to your needs.
Example:
- for Fedora, you’d use dnf instead of pacman
- if your bootloader is broken, you’d want to run grub-install or grub-mkconfig
- if your initramfs doesn’t recognize your new partition, you’d want to regenerate it with the current fstab or crypttab
If nothing else, your files are all fine. You can mount your drive on a different system (like a live USB) and copy all your files.
Thank you all for offering advice. I did eventually get it working and repaired all the packages.
Boot to a liveUSB of the distro of your choice, create a chroot to your install, and then run a Pacman update from there.
Googling “Arch rescue chroot” should point you in the right direction. Good luck!
Will this work from slax linux? I am sorry if I seem like I can’t fix the issue myself seeing as you have given the resources for me to do so but what would be the exact steps to do that?
I’ve never used Slax but it should, boot the liveUSB and enter terminal.
The general process is:
- Boot to live Slax
- Mount your install
- Mount /proc, /sys, /dev
- Enter the chroot
- Check if networking is working
- Attempt to run commands in your chroot
- Exit the chroot
- Unmount everything
- Boot back to your install
Does Timeshift work on Arch? If so I would look into it, saved my ass a few times.
Timeshift definitely works on Arch (I use it before every update) but it isn’t going to help OP if he hasnt taken an image already
Yeah I know, that was a somewhat pretentious “backups” hint.

i dunno why you gotta call me out like that…
Why version them if you could simply have backups? I rarely want old config files…
I don’t know about you, but I tend to make lots of little changes to my setup all the time. Versioning makes it easy to roll back those individual changes, and to tell which change broke what. Sure, you could accomplish the same thing with backups, but versioning offers additional information with negligible cost.
Why not stick them in a git repo?
Versioning is one of those things that you don’t realize you need until it’s too late. Also, commits have messages that can be used to explain why something was done, which can be useful to store info without infodumping comments into your files.
Why versioning and not backups? I get the part of commit messages, but that’s hardly worth the effort for me. If I have a config file which works, I usually keep it that way. And if it stops working, my old documentation is outdated anyway.
you just push the git repo to a remote somewhere and that’s your backup
I use etckeeper to autocommit changes in /etc as git just has better and faster tools to look at the changes of a fle, compared to backup tools.
It’s just so easy to do that there hardly is any point in not doing it.
There is nothing worth of freaking out in your situation. Your files shouldn’t have been impacted at all.
Boot from LiveUSB and reinstall the packages you were updating, maybe reinstall grub too.
There are tons of guides for this in the Internet, like this one: https://www.jeremymorgan.com/tutorials/linux/how-to-reinstall-boot-loader-arch-linux/
Edit: since you probably use systemd-boot, as I can see from your post, obviously the grub part of my comment shouldn’t be done. Replace those parts with systemd-boot reinstallation. Even better if pacman will update it, because there’s probably some hook already to do things manually and you won’t have to touch systemd-boot at all
Can’t help but I just did this myself. Was a fairly fresh install so I didn’t lose anything other than have to reconfigure some stuff and install some things.
Buuuuut
What happened dto me was something crashed during the update and my computer went to a black screen. So I just left it for a bit to hopefully finish even without the display. Turned the computer off and my nvme was just gone. Ended up having to get a new one.
Did systemd or grub not even show up?
Nope. I think the drive just died at a bad time honestly. I’ve had issues with it in the passed and the computer itself came from an e-scrap pile because the water pump for the CPU cooler was dead. Has worked great since swapping that out until the nvme died. Even after installing the new nvme and reinstalling EOS I couldnt see the old nvme.
To add to the other responses, after you recovered your stuff you could probably like moving to an immutable OS if you risk having power issues often, the transactions won’t be applied until everything is done so if anything happens during a transaction you’ll just remain at your last usable state
Note that this isn’t about immutability but atomicity. Current immutable usually have that feature aswell but you don’t need immutability to achieve it.
Yeah you’re right, however searching “linux distro with atomic updates” doesn’t seem to turn up much, as you say, in most cases the two features happen to come together and the distros that have them are mostly known for the former
I had the same thought, but didn’t want to sound insensitive.
Saying “Your fault, using Arch for something important is a bad idea, you should have made a backup before”, while he fears all his important data is gone, would have been rude and very unhelpful.
But immutable distros solve these issues, yes. Since I switched to Silverblue I’ve never been more relaxed than ever. If something goes bad, I just select the old state and everything works, and updates never get applied incompletely like here.
I’m sorry if I sounded insensitive, it wasn’t my intention, just thought that since many others had already given a solution to the data and even OS recovery I could chip in to add something that they might find useful, if they don’t mind switching away from Arch.
I hope mine would be a reassuring suggestion more than anythingYou didn’t! :) You couldn’t have said it better, especially in your answer here!
As I said, I had the same thought as you with immutable distros like SB or Nix.
I just didn’t have much to add as an additional comment besides “Kids, this why you should always backup and maybe use an immutable distro if you can”.
As someone who values robustness and comfort, I wouldn’t touch something arch-based even with a broom-pole.
If I wanted something that’s a rolling release, I would use Tumbleweed or it’s immutable variant.
For me at least, the only pro in Arch is that you can configure everything exactly to your imagination, if I know exactly what I’m doing. And EndeavorOS is pretty much a pre-configured Arch that removes the only USP of it, the DIY-element.
I don’t see myself as competent enough to maintain my arch install, but I can access the AUR with distrobox on every other distro, like Silverblue, too, so I don’t care. The big software repository isn’t an argument for me in 2023 anymore. With distrobox my arch stuff is isolated and if something breaks, I can just forget my two installed apps and reinstall this container in 2 minutes.
It’s just an unimaginable peace of mind for me to know that if I shut down my PC today it will work perfectly tomorrow too. I’m just sick of reinstalling or fixing shit for hours every weekend. I’m too tired for that and have other responsibilities.
But yeah. My thoughts were exactly the same as yours and I didn’t have much more to add besides saying “Hey, do xy that this won’t happen anymore in the future” without sounding like Captain Hindsight from South Park. Context
You took the words right out of my mouth.
Btw that clip was hilarious, I hope I don’t come off like that often lol
