From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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

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'm not sure how funny this will be, but here's how I broke my system twice in a single case. Step by step:

  1. Migrated from Manjaro KDE to EndeavourOS KDE. Kept the previous home directory.
  2. After a few updates, there was a problem with Plasma. Applications were not starting from the panels or the .desktop files (they worked from the terminal. The terminal emulator was in startup and worked that way)
  3. After a few google searches, found out that downgrading glibc would do something, so downgraded... Worked for a while
  4. While using pacman -Syu, I always checked for warnings (foolishly thinking that the downgraded and ignored glibc would cause a pacman warning if it broke dependencies) and there were none. So, the updated OS stopped working due to unmatched glibc. BREAK 1
  5. To fix it, I opened one of my multiple boots (another EndeavourOS) and made a script using pacman -Ql and cp to copy new glibc related files into the broken system (because I was too lazy to learn how to do it the correct way with pacman and chroot didn't work because glibc is needed by bash).
  6. Turned out the script I made was wrong and I hadn't checked the intermediate output from pacman -Ql, which was telling cp to copy the whole /etc /usr and other directories. (just if I hadn't given the -r to cp) BREAK 2

In the end, I just made a new installation, this time with a new home and hand-picked whatever settings I wanted from the previous home, Viva la multi-HDD
