So my personal anecdote also involves mint - I've set one up for someone years ago(probably around 2013-2014) and you're right, it had no issues. However, when I came over to visit last year I wanted to do some maintenance, so "apt-get update" and "apt-get upgrade" would be the start.

You might have had that problem in 2013, since Mint editions were based on the latest Ubuntu release. But since May 2014, all releases of Mint are based instead on Ubuntu LTS release.

The main problem is that until it gets better it ends up alienating a lot of people because the standard support from the community is "did you RTFM?"
