How did we ever live before apt-get?

The Debian Package Manager turned 25 years old last year, and apt-get has been around for two decades now. I am old enough to remember manually installing packages using RPM and having to go around searching for dependencies.

And building a lot of software from source code using to ./configure; make; make install — and having to search around for packages to fix missing dependencies during the configure process. It’s very rare these days to have to build something from source code, unless you are tweaking some of the lines of code.
