I can't tell you about all of the times, but I will tell you about one time it broke and why. I did a debian clean install. Then I added the Spotify repository. Then I apt-get spotify. The script hung and then apt got into this weird loop. I had to add exit 0 to a script to fix it. This isn't what i want to do. I have over 10 years experience with Linux. I've even done Linux from scratch. I learned it already, this is not the problem. The problem is that Linux doesn't have stability currently that satisfies my needs and life goals.
