Question: What was the worst mistake you made in Linux?

So... Because I've finally upgraded my PC (rip money on bank account) I can now run a VM with Linux all the time that isn't slow as a snail.
I installed Linux mint, with 4Gb of Ram and 6 cores, and it runs like a brize, while I play on windows and stuff. BTW I'll be using the VM for programming stuff, since I'm finally at home (homesick because of burn out), when I'm better I'll finally have the patience and memory to learn new stuff and get my projects up and going.
And because I've never really used Linux I'm watching YouTube videos about Linux, and found a Perl I've watched before, #Linux Sucks
And It's great... I get so many laughs, but also, learn stuff I didn't know, like, how Linux Pros make mistakes that Windows users can't even do, like breaking the OS.
So... I would love to know, what was the worst mistakes you ever done on Linux? How did you brake you're system?
BTW this would also be great for noobs like me to not make them... I hope. Since I'll be moving full Linux when I'm comfortable.

BTW @dfox this would be a great wk ...

    I recently run that on my machine at work because people told me, fork bombs are not breaking your system anymore.
    They were right, my machine became unresponsive for several seconds but soon the Terminal crashed and everything was working again

    dist upgrade without reading what it was going to uninstall. . . It uninstalled pretty much everything.

    I once accidentally added an ubuntu beta repository and let it do an apt upgrade and apt dist-upgrade.

    This updates a lot of the packages and ubuntu itself to a beta version. Some packages did not get updated but still broke because of dependencies that did get updated.

    It was not a fun night fixing that.

    Bitbucket has Gb and a build limit to 50 minutes, what does that mean? and does GitLab has the same limits?
