[Solved] Had a power outage while updating my fedora system, and now dnf has file conflicts. Is it recoverable?

This is honestly why anyone and everyone should invest in at least a small UPS that can keep your PC powered for at least five minutes so in this kind of scenario you can cancel the update, shut down safely, and resume when the power is back.

Or use a system that has rollbacks so you can use the last known good configuration

Btrfs snapshots + Timeshift that is configured to run pre-update is great for this, though I cannot remember if Fedora’s layout is compatible with Timeshift’s expected configuration.

OP, If you really want to go 100% with this, something like NixOS (which is definitely an extreme investment) or an Atomic distro like Fedora Silverblue works very well for this.

As you mentioned, with Fedora the best alternatives are immutable spins. Updating means downloading a new base image, applying overlays and additional installations to it and on the next reboot you start from that image. You can configure it to keep as many previous versions as you need and boot into those directly on startup. Since you never change your current image once it’s built, you can’t break a known good system. You can only ever break your next version and in that case, just boot the previous.

I’ve created an Ansible playbook that configures a vanilla Kinoite the way I want it. No need to back up the system if I can recreate it with less than a megabyte of text files. Secrets are in my password vault, personal files are in my personal cloud and get synced to and from the laptop continuously. I would never go back to backing up system files as opposed to recreating it with a playbook. That seems so wasteful in hindsight.

This is why my main personal machine will always be a laptop.

Snot Flickerman@lemmy.blahaj.zone · 9 months ago

I have far too many networking appliances for that, myself.

Infiltrated_ad8271@kbin.social · 9 months ago

Ideally yes, but using btrfs with something like timeshift is enough.

LostXOR@kbin.social · 9 months ago

Any recommendations for a fairly cheap one? It would definitely come in handy.

Snot Flickerman@lemmy.blahaj.zone · edit-2 9 months ago

Well for one, are we in the same country? US here. I’m not as savvy on pricings in the EU or anywhere else for that matter.

For two, it’s helpful to assume what you need is based on your PCs max wattage input imho. That way, if it can run your machine drawing max power (wattage) for 5 minutes, it can run it for longer when its drawing less power than that.

dnf upgrade And package-cleanup --cleandupes Should have fixed it.

First things first, run the command you want to run and provide us the error output.

nossaquesapao@lemmy.eco.br · 9 months ago

I was running dnf update when the system was shut down, and I rebooted when the power was back. The system apparently booted normally, and I tried to complete the upgrade process, to avoid issued. Now, the “dnf update” command shows the error message I posted.

In the original post, the error was in portuguese. Now I changed system language to english and posted the entire output of dnf update in the original post, to make it more readable for the community.

prettybunnys@sh.itjust.works · edit-2 9 months ago

I’m not seeing your error output but I do see your paraphrasing of the error output.

Idk if it’s my app not showing it or what.

It was the Memmy app everyone, shame

Snot Flickerman@lemmy.blahaj.zone · edit-2 9 months ago

Error: Problem: cannot install both at-spi2-core-2.50.1-1.fc39.x86_64 from updates and at-spi2-core-2.50.0-1.fc39.x86_64 from fedora

conflicting requests (try to add ‘–allowerasing’ to command line to replace conflicting packages or ‘–skip-broken’ to skip uninstallable packages)

Not OP, but this looks like the error message.

prettybunnys@sh.itjust.works · edit-2 9 months ago

Are you using markdown or something?

My app is only showing “Not OP, but this looks like the error message” and nothing else.

we’re out here troubleshooting all kinds of shit

Snot Flickerman@lemmy.blahaj.zone · edit-2 9 months ago

I am, I will remove the codeblock markdown.

Edit: removed, let me know if you can see it now.

prettybunnys@sh.itjust.works · 9 months ago

Yes, and that is the nail in the coffin of the Memmy app for me.

Thanks!

BigFatNips@sh.itjust.works · 9 months ago

Shows up fine on voyager (Android)

prettybunnys@sh.itjust.works · 9 months ago

Memmy App on iOS and it doesn’t seem to show code blocks. Lame

nossaquesapao@lemmy.eco.br · 9 months ago

That’s strange, but anyway, I managed to solve the problem and edited the post with the solution. Thank you for the support.

PseudoSpock@lemmy.dbzer0.com · 9 months ago

I suggest a filesystem that supports taking snapshots in the future. It’s a lifesaver for moments like these.

nossaquesapao@lemmy.eco.br · 9 months ago

I’m using btrfs, but I still need to read more about how it works. I will try to use this experience as a motivator, thank you.

RiderExMachina@lemmy.ml · 9 months ago

Are you sure its removing those packages and not updating them?

nossaquesapao@lemmy.eco.br · 9 months ago

yes, the last 2 mentioned commands throw the error below and won’t continue the operation:

Error: 
 Problem: The operation would result in removing the following protected packages: systemd, systemd-udev
