Arch doesn’t break all the time either, but it’s a meme and therefor 100% true.
An arch user defines “doesn’t break all the time” as “I have to read the news before every update and apply a manual intervention a few times a year, and there’s only been like one time in history that an update made people’s installs unbootable despite them taking those precautions”.
A Debian user defines “doesn’t break all the time” as “I have a cron job running that periodically runs sudo apt update. I have no idea when it does this or what’s changing when it happens and nothing bad has ever happened to me”.
Like, the fact that unattended-upgrades comes pre-installed and enabled by default (for security updates) in Debian GNOME vs the fact that informant exists to force you to read the news in Arch before you update should tell you that the two distros exist in two different universes.
