For me, Windows is thousand years ahead in this regard. I download software, and run it. And it works 99.9% of the time. Yes, I have a chance of getting a virus. Happened one time in 30 years I'm using Windows. (More in DOS times). Linux, I got burned again yesterday. Proxmox distribution has no package I need in their repository. I am trying to use Ubuntu package - does not work. I try to use debian - too old version. How do I solve this? By learning some details of how the Linux distributions and repositories work, struggling some more and finding customly built version of .deb. Okay, I can do it, kinda, but what about non-IT person? Software without dependencies is awesome. So, docker is something I respect a lot, because it allows the same model (kinda).
