What distro are you using that has these issues? My Debian server has been running solidly for years without crashing or (automatically) updating. I've also never had any problems with QA or package management; everything installed with the system package manager has always run, installed, and updated smoothly. I'm not a linux expert, but what you described are all issues I associate exclusively with Windows and, to a lesser extent, recent MacOS, both of which I also use frequently.
