Linux

A few years ago I was having obscure audio problems on Ubuntu so I tried replacing pulseaudio with pipewire. I was feeling pretty cocky with using the package manager so I tried

sudo apt install pipewire

Installed successfully, realized nothing changed, figured maybe I had to get rid of pulseaudio to make it stick.

sudo apt remove pulseaudio

Just two commands. Instant black screen, PC reboots into the terminal interface. No GUI. Rebooting again just brings me back to the terminal.

I fixed it eventually, but I'm really not very computer literate despite using Linux, so I was sweating bullets for a minute that I might have bricked it irreversibly or something.

sudo apt upgrade -y

To this day I can’t figure out why it killed the GUI and all terminal commands on a Mint install…

I suppose it doesn't quite qualify as breaking the system in a funny or stupid way but it certainly was one of those stupid things that was easy to fix after a ton of trouble shooting, ignoring the issue for a while and trying to fix it again.

So i had an old pc where I had a failed hard drive which I replaced. Obviously I also accidentally unplugged my optical disc drive and plugged it back in. Now that failed drive was just a data drive so the system should have booted up no problem since the os was on a SSD but instead it got a kernel panic and got stuck at boot. Since it was late I left it at that and came back to that the next day where it would still not boot. So I unplugged the disc drive and looked up what it could be. Tried a ton of different possible solutions but every time I added that disc drive it would panic.

I eventually kind of gave up and just didn't use that disc drive at all and just had it as a paperweight in the system. Unplugged and all that. When my replacement SSDs for my old data drive and backup drive came in I tried again to get that optical drive working but to no avail. So I unplugged it again, got it all set up and ran into another issue where for some reason Linux couldn't properly use my backup SSD. So I investigated that as well and trough some miracle found a post on the forum from my Mainboard manufacturer... Turns out that particular Mainboard had a data retention chip on it that didn't like Linux.

So naturally I just plugged everything into the data ports that were not controlled by that chip and it all worked as intended.

Stupid dumb chip on a Mainboard, all I had to do was try the simple idea of unplugging and trying a different connector but instead I did all that other stuff first that didn't work and cost me so much of my time.

Moral of the story, when in doubt try and put stuff on different connectors and see if that fixes it. Might just be a dead connector for all you know. Or an incompatible chip on the Mainboard.

FWIW I bought that Mainboard long before I switched to Linux and didn't plan at all to switch at the time. But that's a different story.

The only time was within a VM. I accidentally wrote

rm -rf ./* while my cwd was /

I use absolute paths with -rf now, to prevent the error again.

Every other breakage I had was with apt shitting itself. It has always been fixable just annoying.

I now use Fedora, to prevent the error again.

This was pre-linux for me but something you can still do in most distros so I think it's a valid story.

In 1999 I was using Napster on computer running MS-DOS. I was 12 years old and an aspiring open media enthusiast/stupid script kiddie. I was using the file explorer interface in Napster and accidentally gave access to my entire C drive. I also had opened ports to share certain media and to fuck with my friends using daemon tools (back then you could do stupid stuff like control a friend's desktop with certain versions of daemon tools). Immediately I started receiving packages called things like "sleep.tight.tiny.mite" and I knew I was fucked so I clicked in the Napster interface and clicked "delete" and deleted my entire active drive.

I panicked and installed the only operating system we had which was a random copy of Red Hat. When my dad came home I pretended like it had always had Linux on it. I do think he was more impressed than mad.

Not really a "braking my linux setup", but still fun as hell! Back in university, a friend of mine got a new notebook at a time... we spent the night at the university hacking and they wanted to set the notebook up in the evening. They got to the point where they had to setup luks via the cryptsetup CLI. But they got stuck, it just wouldn't work. They tried for HOURS to debug why cryptsetup didn't let them setup LUKS on the drive.

At some point, in the middle of the night (literally something like 2 in the morning) they suddenly JUMPED from their seat and screamed "TYPE UPPERCASE 'YES' - FUCK!!!"

They debugged for about six hours and the conclusion was that cryptsetup asks "If you are sure you want to overwrite, type uppercase 'yes'". ... and they typed lowercase. For six hours. Literally.

The room was on the floor, holding their stomach laughing.

Actually, I have a story that I'd consider an achievement even though it was extremely stupid and by all accounts should've bricked the system but didnt.

So I was on windows and wanted to install linux as a dual-boot on the main drive. The problem was that my mobo didnt like this particular and the only flash drive I've had, dropping it out mid-boot, before I got any usable terminal, so a usual install method wasn't an option. So I had this crazy idea to start a vmware vm in windows and pass the linux iso and the boot drive directly to it and try to install it live over the running system. Unfortunately, vmware guys thought of this and there's a check that disallows passing the boot drive to vms. So i created a bunch of .vmdks for another drive and fiddled with them in notepad until I somehow managed to trick vmware and at some point it started booting the same windows copy that I was sitting on. I quickly powered it off, added the linux iso and proceeded to install like I usually would. It did involve some partition shuffling, but, somehow, it went smoothly, linux installed, grub caught on, and even windows somehow survived, even though it was physically moved around on the disk. It serms that vmware later patched this out, because later in an attempt to re-create the trick of running the same copy of windows twice, but after updates to both windows and vmware, I was met with the same old error that boot drive is not allowed when trying to add that same virtual drive I had laying around.

I can't remember what I did to break it, but back when I was in high school I was tinkering right before class and rendered my laptop unbootable. I booted into an Arch Linux USB, chrooted into my install, found the config file I messed with, then reverted it. I booted back into my system and started the bell ringer assignment as quickly as I could. I had one minute left when the teacher walks by, looks at it, and says that I did a really good job. She never knew my laptop was unbootable just 2 minutes earlier.

I was testing a custom initramfs that would load a full root into a ramdisk, and when I was going to shut down I tried to run rm -rf --no-preserve-root / to see what would happen, since I was on a ramdisk anyway. The computer would not boot after that because it nuked the UEFI options.

chown 777 everything

Can't say I have any interesting stories. Most of mine are just the head-scratching "I don't know why that didn't work; guess I need to reinstall" kind of story. Like enabling encrypted LVM on install and suddenly nothing is visible to UEFI. Or trying to switch desktop environments using tasksel and now I have a blank screen on next reboot. That lame kind of stuff.

My coworker though... he was mindlessly copy/pasting commands and did the classic rm -rf $UNSETVARIABLE while in / and nuked months of migrated data on his newly built system. He hadn't even set up backups yet. Management was upset but lenient.

rm -rf /var

I don't know what I was thinking on to type it 😅

I deleted the entire taskbar.

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

sudo apt remove python3

Thinking I would install a more recent version. 😂

I had rEFInd and GRUB installed entirely by accident, and a botched update for Arch hosed my entire EFI setup making it impossible to boot Linux or Windows w/o a LiveCD. Thankfully it self repaired once I nuked rEFInd. I ended up going back to Ubuntu, but I hate snaps. I still would recommend Arch for most Linux users who want the power windows.

Let's see: Unintentionally making a proxy accessible to anyone online

Accidentally deallocating an ext4 partition and then having to run testdisk on it

Trying to manually create a grub entry and corrupting the bootloader

Installing a arch derivertive and having it silently overwrite grub

Installing puppy Linux and then trying to get it to use apt

Incorrect use of ppa's on mint resulting in very old packages being installed

And many others besides

I wanted to move my Arch VM to bare metal, so I copied out all the important bits. Then I wanted to move that copy to a new drive so I could boot into it.

I THOUGHT I'd MV all the files in the Arch install's etc directory using sudo MV /etc ...

I also (somehow) mashed my install's etc with Arch's and bungled both, with no live CD to help.

I learned a thing or two about absolute file paths...

Deleted my entire efi partition while trying to install some grub themes.

And then my backup didn't work when I tried to restore it.

I have pretty colours now though, so it was all worth it :)

At one point I had the coolest Ventoy USB; CyberRe, LABEL=hakr. But then I got a new computer and apparently the ssd was /dev/nvme0n1 instead of /dev/sda. While I was installing Arch, When I created a new GPT partition on /dev/sda, it wiped my beautiful Ventoy 😢

Before installing Arch on a USB flash drive, I disabled ext4 journaling in order to reduce disk reads and writes, being fully aware of the implications (file corruption after unexpected power loss). I was confident that I would never have to pull the plug or the drive without issuing a normal shutdown first. Unfortunately, there was one possibility I hadn't considered: sometimes, there's that one service preventing your PC from turning off, and at that stage there's no way to kill it (besides waiting for systemd to time out, but I was impatient).

So I pulled the plug. The system booted fine, but was missing some binaries. Unfortunately, I couldn't use pacman to restore them because some of the files it relied on were also destroyed.

This was not the last time I went through this. Luckily I've learned my lesson by now

Renaming a mount point while mounted was a fun experience in losing data back in the big box Redhat 5.0 days.
