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?

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.

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.

There was definitely a time when python3 was not recommended and plenty of scripts weren't yet differentiating between the two. Everything was breaking back then.
