What's (are) the funniest/stupidest way(s) you've broken your linux setup?

Tinkering is all fun and games, until it’s 4 am, your vision is blurry, and thinking straight becomes a non-option, or perhaps you just get overly confident, type something and press enter before considering the consequences of the command you’re about to execute… And then all you have is a kernel panic and one thought bouncing in your head: “damn, what did I expect to happen?”.

Off the top of my head I remember 2 of those. Both happened a while ago, so I don’t remember all the details, unfortunately.

For the warmup, removing PAM. I was trying to convert my artix install to a regular arch without reinstalling everything. Should be kinda simple: change repos, install systemd, uninstall dinit and it’s units, profit. Yet after doing just that I was left with some PAM errors… So, I Rdd-ed libpam instead of just using –overwrite. Needless to say, I had to search for live usb yet again.

And the one at least I find quite funny. After about a year of using arch I was considering myself a confident enough user, and it so happened that I wanted to install smth that was packaged for debian. A reasonable person would, perhaps, write a pkgbuild that would unpack the .deb and install it’s contents properly along with all the necessary dependencies. But not me, I installed dpkg. The package refused to either work or install complaining that the version of glibc was incorrect… So, I installed glibc from Debian’s repos. After a few seconds my poor PC probably spent staring in disbelief at the sheer stupidity of the meatbag behind the keyboard, I was met with a reboot, a kernel panic, and a need to find another PC to flash an archiso to a flash drive ('cause ofc I didn’t have one at the time).

Anyways, what are your stories?

MTK,

sudo apt autoremove

Who ever made this shit and then decided to always show you this message that you should do it. What a dick

Head,

I deleted the entire taskbar.

ArmainAP,

Somehow I found ways to remove and break the GUI multiple times in multiple ways in multiple distros.

Different scenarios, different times, different issues trying to “fix”. My usual fix after this was always to copy what I think I still had important and then move on with a reinstall.

Recently I have been playing with ZorinOS and broke it in the same way by fidgeting with pipewire. Distro hoped to Fedora Silverblue due to the immutable filesystem. I wonder if I will break this one in a way I cannot revert it easily with rpm-ostree. I almost feel challenged.

HuntressHimbo,

So I am sort of an embedded developer, and I like to mess around with weird configurations. So the craziest experiment I did was trying to reflash a rasberry pi from a system running in the pi’s RAM. It honestly might have worked, but during the prep work I forgot to resize the filesystem before mucking with the paritions and had to reflash the normal way before I could try again. Ended up just turning it into a pihole instead, but I still learned a lot about pivot_root

marionberrycore,

About a year ago I somehow fucked up installing a new window manager on my tablet so badly I had to start from scratch - to this day I have no idea what happened there, but it just wouldn’t boot properly or anything after that 🤷 I needed it for school pretty quickly though so my top priority was getting it working again, so I set up a fresh install instead of continuing to fuck around.

Not the same level of destruction, but I fucked up my first ever install a couple months in trying to resolve dependencies related to python and wine, which is why I’m more interested in sandboxing whenever feasible these days. After only two months I guess I had been fucking around with linux long enough to have a little too much unearned confidence, lol

olutukko,

I dont remember what I did when I was stoned. The next day I tried to do normal sudo dnf install and it doesnt recognize any command anymore. I tried restarting it and I cant login anymore because the login scripts dont work. Not that funny but just happened and weirdest way I have broke it

StorageAware,

It was only in a container on a Chromebook, but I’ll share it anyway. One time, I had installed Android Studio but found it mildly annoying that I got a line when using apt about Android Studio and some error on a certain line of this one file. I believe the file was something related to dpkg, and after changing some things within the file, I seemed to have broken apt. Luckily, I had a backup, but it was a few days old, so I had to reinstall some apps.

exocortex,

Oh, i have a brilliant one:

A few years ago i spent a lot of time converting .flac-files into .ogg-files in order to put on my oldschool iPod. As I did a lot of repetitive typing - entering $dir / for file in flac ; do convert etc / mkdir -p $somewhere/$artist/$album / mv $somewhere/.ogg->$new_dir/ and so on - I thought: “hm lets just write a loop over loops for all the artists here and then all the albums and at the same time create the nested directories somewhere else… hm actually in the home directory… and later love everything on the iPod at once.”

so i was in my music folder with the artists-folders i wanted to convert. i did something wrong

So i did my complicated script directly in the shell. I made something wrong and instead of creating a folder “/artist/album” I created 3 folders in my current working directory: “”, “artist” and “album”. hmph dammit gotta try again… but first : i have to clean up these useless folders in the current dir. so i type of course this: "$ rm -r ~ artist album " after about 5 seconds of wondering why it took so long i realized my error. o_O I stopped the running command, but it was (of course) too late and i bricked my current installation. All the half-deleted config files made or impossible to start normally and extremely tedious to repair it by hand, so i reinstalled.

forvirretfugl,

Wanted a cool bootscreen on my Nixos machine - commented out the bootloader to troubleshoot, why my meme-boot-picture wouldn’t show - after rebooting, it loaded straight into the BIOS and finally realized what I had done… Was able to fix it thankfully

inetknght,

I was running Fedora. Something like 27 or so. I needed drivers. I don’t remember if it was AMD or Nvidia, but they were only available on RedHat.

So I downloaded the RedHat drivers for the GPU and forced it to install. It worked! It was great.

Then when I updated the distro to the next release… everything failed. It was dropping into grub, but no video was output. Ooof.

So I ended up enabling a terminal console and connecting to it via a serial port to debug. I had to completely uninstall that RPM and I was never happy that it was properly gone. So a few months later I ended up reinstalling the whole OS.

On the plus side, I learned a lot about grub and serial consoles. Worth it.

and a need to find another PC to flash an archiso to a flash drive ('cause ofc I didn’t have one at the time).

you can do that from your phone using etchdroid

i don’t remember ever breaking my system in a terrible way, but when i started using linux (with linux mint) i uninstalled ca-certificates and i think that uninstalled the whole DE

gianni,

Just yesterday I overwrote some pacnew files and borked user authentication for myself. Very rough time

AlijahTheMediocre,

I somehow locked myself out of sudo when trying to give my user permission to read serial devices.

Had to reinstall.

FollowingTheTao,

I wanted my top bar in DWM toshow the time, so I put the script directly into the .xinitrc file instead of the path to the script.

med,

Ubuntu GUI/apt fail

Back when I used ubuntu, Unity was stuck with old gnome packages. This meant that the version gnome-terminal packaged with ubuntu (up to at least 18.04) didn’t have text reflow on window size changes.

You could add the upstream sources, upgrade the specific text reflow package only, and then disable the sources.

I forgot to disable the sources, or typed dist-upgrade (this happened multiple times…). Broke the whole desktop/lightdm setup with half upgraded packages, and half removed packages (for preparation to install new versions). Way easier to reinstall the os than to disentangle. Unity was a mess then anyway.

Moral: Actually read the package change summaries when doing updates/removes/installs, and [ y/N ] means actually check what the fuck you think you’re agreeing to.

BtrFS snapshots for idiots

I’ve also run automated snapshots on my btrfs partition, then run out of space doing multi-hop system upgrade on fedora (dnf has a plugin that creates a snapshot every time it kicks in.

You can imagine there were many changes happenning per snapshot, and I effectively could have rolled back 4 major fedora versions… Til I ran out of space.

I couldn’t get a replacement drive in time, and I had an hour to rebuild my laptop before needing to be on a customer site, so sadly I couldn’t preserve my drive for later investigation. My best guess is the high-water-mark was configured incorrectly, and somehow it was able to ‘write’ data past the extents of the filesystem.

Rollback did work for my home partition, but I had to mount it from another OS to get it to work - so no data loss!

By that time I’d already reinstalled the os to the root partition/subvolume however, so I couldn’t determine the exact cause of failure :(

Moral: Snapshots are not backups, and ‘working’ is not ‘tested’
