I think he is not angry at the package manager, he is angry that the package manager failed, and he had to use the terminal to fix it. And it IS not acceptable, I use Fedora myself, and every time this happened I got REALLY, REALLY upset, if I am using a GUI package manager, why the hell I should need to use console to fix it when it breaks? Why there is no option on the GUI to do that? Also I had a machine that I had to install a kernel module to put sound on it... Linux still have some serious issues with some hardware (mostly audio and radio-based communications, I've heard printers are problematic too, but it is years that I don't own a printer)
