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?

I’ve broken systems far too many times in the last 24 years, since Mandrake 6.x, to count:

  • I’ve dd a disk or more
  • I’ve rm *
  • I’ve chmod
  • I’ve brought down the network, with every intention tar it would come back - on a remote box
  • I’ve failed to RTFM far too many times
glibg10b,

I wanted to use fio to benchmark my root drive. I had seen a tutorial saying that the file= parameter should point to the device file, so I pointed it at /dev/sda. As you might expect, the write test didn’t go so well.

devnull406,

Connect via ssh to my home server from work

Using a cli torrent client to download stuff

Decide I need a VPN.

Install VPN again from CLI

Run VPN which disconnects my ssh connection

Even when I get home, the server is headless so I have to locate a keyboard and mouse before I can fix.

fl42v,

Dang, similar stuff happened to me on nixos. Had to instruct one of the relatives on how to reboot the machine and choose a previous generation in the boitloader 🤣

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.

janabuggs,

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.

“Just pretend it’s always been Linux” is a bold move. I salute 12-year-old you o7

I once deleted the network system in alpine. I’d been having some trouble with with the default one (I think wpa_supplicant) so I decided to try the other one (I think iwctl). But I thought that there might be problems with havung both of them so before I installed iwctl I deleted wpa_supplicant (thinking that it was more of a config utility than the whole network system), only to find that I couldn’t connect to the internet to install iwctl.

Petter1,

You could have used the netplan yaml file 😇 or chroot from live distro

fl42v,

Oh, I just remembered another one or three. So, resizing the partitions. My install at the time had a swap partition that I didn’t need anymore. Should be simple, right? Remove the partition and the corresponding fstab entry, resize root, profit. Well, the superblock disagreed. Fortunately, I was lucky enough to be able to re-create the scheme as it was, and then take my time to read the wiki and do the procedure properly (e2fsck, resize2fs and all that stuff).

Some people I’ve met since, unfortunately, weren’t so lucky (as far as I remember, both tried to shrink and were past mkfs already) and had to reinstall. The moral is, one does simply mess with superblocks; read the wiki first!

papertowels,

Not strictly Linux related, but in college I was an IT assistant. One day I was given a stack of drives to run through dariks boot and nuke.

I don’t remember exactly what happened, but I think midway through, my laptop shut off.

Guess who picked the wrong drive to wipe with DBAN :)

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

FractalsInfinite,

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

papertowels,

The first time I enabled o auth for something self hosted, I gave access to anyone with a Gmail account.

On OpenSUSE, in Yast bootloader tool, there is a checkbox to to do something like locking the bootloader (it has been a while, I don’t remember the exact thingy). Rebooted and oh, surprise, the bootloader was locked… Which mean Grub didn’t load.

I had to reinstall the whole OS 🤣

Types

rm -r -f Presses strg+v (instead of strg + shift + v)

Hits enter

Maschine proceeds to delete the home folder as the garbage that comes when pressing normal strg+v gets interpreted so…

Installed python3 before it was made the native python on the dist. Half broke everything, including apt & python. So I uninstalled it, and then everything was broken. Finally got python3 reinstalled, and lived with it kindof working & awful distribution updates.

I have finally freed myself of that prison last month, by nuking everything and starting fresh.

martinb,

You can have both python 2 and 3 on the system. It just depends upon which is the default as to how much you break it 👍 The symlink to /usr/bin/python is the important bit for most software. For deb-based at least, update-alternative is your friend.

HotChickenFeet,

I’ll happily say I must have overlooked something, but I did try using update-alternatives. I don’t remember all the nuts and bolts from the start, but it involves python3 and distribution upgrades. I spent a good number of nights over the years trying to unmess it up, and am happy to never think about it ever again.

sudo apt remove python3

Thinking I would install a more recent version. 😂

9488fcea02a9,

I didnt break anything, but there was this one time i was setting up a new lxc container i had just spun up. I installed nginx, and a bunch of other packages, started writing new config files… Then i noticed my prompt was user@desktop$ instead of user@server$

Whoops… I was in the wrong terminal window, typing commands into my desktop instead of the container i was setting up.
