A few years ago I installed CentOS (because it was supposed to be one of the most stable distros at the time) and my mom was happy using LibreOffice to make her documents.

I thought the shortcut was misplaced or something, but actually CentOS had a bug where the graphical update utility uninstalled itself with one of the updates. I wonder how computer illiterate people are supposed to fix something like this without assistance :)
