Such a weird flex. Debian sure wasn't Slackware, it was one of the easiest distros to install and manage. It took years until commercial distros like RedHat could catch up.
I remember my first time trying to install Debian, being a total noob to the whole thing. I thought parts of the installer were broken, because I couldn't toggle TUI checkboxes. Every time I tried, the installer would instead jump to the next screen.
Years later, I figured out that you're supposed to use the spacebar to select/toggle UI elements, not the Enter key. Nobody told me that, and the text-mode installer certainly doesn't tell you!
Ubuntu 11.04, on the other hand, was no trouble to install.
