You seem to be reaching for pretty advanced solutions – Docker and HA both require you to read a lot of documentation to get started. Bottles is also a powerful and flexible tool, which is the opposite of simple.

What game are you trying to run? If it’s on Steam it should be a no-brainer, otherwise Lutris can simplify a lot of things.

I doubt you actually need Docker for anything, unless you have a specific use case I would just abandon that. For your lights, I would try searching for “home assistant [model/brand of lights]” and see if you can find a setup that someone else has gotten working that you can mostly copy.

Use an operating system like Linux Mint. It’s very simple. Steam can solve the Wine problem, this can be done by adding a new game into your Steam library. Remember that all the distros have certain goals in mind.

Stick to it! I know it seems overwhelming in the beginning, but you will get used to it at first and then get better with time.

Docker won’t make much sense if you don’t understand the underlying Linux systems and/or applications.

It’s similar with Wine and Bottles. If you don’t get what’s in the bottle, then running the bottle won’t make sense.

Find tasks that run on the native OS. learn to manage Linux itself. skip containers, Snap, virtual machines, etc.

try running a web server using httpd or something.

Don’t feel bad, I’ve used Linux since 1995 and don’t have enough skills to use Bottles.

I do however game a lot, using mainly Steam and Heroic. You can try to start there.

A thing about Linux is that there’s usually like 10 different ways to accomplish something. If you hit a dead end in terms of your ability or tolerance for frustration… just go back to square one and find a different approach. For games, I recommend starting with Steam.

Portainer helped me get my head around docker images. And docker hub sometimes has the steps to configure the container, and sometimes not; many assume everyone knows how to pass bind or volume mounts and bridge or host network stuff.

I played with portainer a while to visually see what thing do.

Then it led to command line and yaml configs stuff after that. Its a learning process.

I’ve been daily driving Linux since the early 00s and docker confounds me too, especially the networking. I’m not familiar with bottles. I just play all my games on steam and it’s seamless.

So… you receive plenty of great technical advice, I won’t go there.

I’m sure your title is wrong. I know for a fact that there is plenty of things you did with Linux that looked until then impossible. They do look impossible to most people today. So… yes there are plenty of things you don’t know how to reliably do but you eventually will manage!

I did read a bit from the Greater Good Science Center in Berkeley https://greatergood.berkeley.edu/ and there was a piece specifically on “everytime” or “always” as basically shortcuts during arguments that reframe the situation incorrectly. You surely meant to say “I often get frustrated trying new things on Linux” instead. It sounds like I’m nitpicking, yet simply rephrasing gives a totally new outlook to the situation. We all, literally ALL of us, do struggle when we try something new. We often fail but if we keep on trying, get methodical about it (what was the error message? did I try something similar before? how does it actually work? who could help me? etc) then you are bound to succeed.

So no, you are not the problem. No, you are not an imbecile. No, you do not always fail!

Some distros and technologies can be more complex.

For Home Assistant, consider using Yunohost. It doesn’t require Docker skills. You can find step-by-step guides on their website.

I guess gaming with Linux has always been tricky, you can check ProtonDB to see which games are easily compatible with Linux.

If I were you, I’d make sure to tackle one thing at the time, and set aside some time to figure it out, where the goal is not to for instance play games, but set up a game for play later. That way you can focus on the first part, instead of trying to rush that. So for example, when you are trying to set up Home Assistant, spend time just getting Docker to work first. I’ve fallen into that trap many times before, where I ended up not reading the messages properly because I was impatient and just wanted to get to the end fast. Once you get more familiar with Linux, this stuff gets quicker because more of the steps involved with any task is familiar to you already, and the troubleshooting threads you find on different forums are less Greek.

For specifics:

1. For Docker, when you feel ready to try that again, I’d recommend setting it up together with a GUI, like Portainer. If you follow the official guides to install Docker and then Portainer, you should have a web UI accessible that makes dealing with containers easier. I generally like doing things in the command line, but for containers, I prefer to have a GUI.

2. When it comes to Home Assistant, I’d honestly go for either Home Assistant Green or Yellow from Nabu Casa (you’d support the Open Home Foundation directly this way). If you want to set it up yourself, I’d go the route of a dedicated single board computer, like a Raspberry Pi, and use Home Assistant OS. I tried to set it up as a container as well before, but there are certain limitations you avoid by just running their OS directly on dedicated hardware. It’s been running smoothly for me since I set it up on my Raspberry Pi 4.

3. It is good to learn about Wine and Bottles, but I’d start out with Steam (and Proton), Heroic and Lutris. I’ve had much headaches getting stuff to run properly on Heroic and Lutris, but I think the trick here is to avoid Flatpaks for these sorts of things, because there are many dependencies, and you are dependent on a good permissions setup for Flatpaks. Your mileage may vary though, I’m sure there are plenty of people with painless experiences with Flatpaks here.

Before using docker u need learn how to use it,it would be problem no matter what os if u don’t know how to use this technology.Bottles yes or portproton,storage scan u can use gnome disk storage analyzer

I opted to install a game, fail.

I don’t remember ever getting anything to work in Bottles. PlayonLinux is much better (for any sort of app, not just games).

which distro and hardware config? Can’t speak to docker as I don’t use that any more, I’ve yet to get stuck into homeassistant, but games are just click and run on most distros with steam?

Ok, lots of answers focusing on the game, so I think you have plenty of suggestions on what to try there. That being said I have never heard of bottles, I’ve used raw wine and PlayOnLinux before Steam integrated Proton so now I just use that.

For docker it can be daunting, and home assistant is not an easy thing to setup. The thing with docker is that it can be very complex, but you don’t have to worry about the majority of it. I assume you have docker installed, enabled and your user is in the correct groups. Unfortunately Mint/Ubuntu don’t have docker in their normal repos so you probably had to add the docker PPA and install from there. Let’s run a couple of commands to ensure all went well:

sudo systemctl status docker

This should show you the status of the docker daemon, and it should say that it is Active. If you get a no such service type error then docker is not installed, if it’s not shown as active then the daemon is not started and can be done so by running sudo systemctl start docker (and you can replace start with enable for it to happen at boot). If it’s Active then awesome, let’s check that your used can run docker commands, try running this: docker run hello-world if that fails but sudo docker run hello-world works then your user doesn’t have access, you want to add your user to the docker group sudo usermod -aG docker $USER and reboot.

Ok, docker hello world is working, what now? Now, I assume you have some idea of what docker is, but in a (wrong but simple) way you can think of it as virtual machines. Let’s try to run some cool stuff in it, there are two main ways, running a long complicated command, or writing those parameters on a file and running a simple command. This file is called a compose file, and should be named compose.yaml or docker-compose.yaml. let’s try that, create a folder called silverbullet (just because that’s the service we will try, it is a note taking app that I really like) and in there create a file compose.yaml and write the following content there (everything starting with # is a comment I added explaining what that does, and can be removed if you don’t want it):

# This defines all of the services we want to run
services:
  # This is the name of the service, it can be whatever you want
  silverbullet:
    # The image is the actual thing you want to run
    image: ghcr.io/silverbulletmd/silverbullet
    # This tells docker to restart the service if it closed for whatever reason, unless you specifically tell it to stop
    restart: unless-stopped
    # This will set environment variables inside the docker.
    # different services might require different environment variables set
    environment:
      # silver bullet uses SB_USER environment variable to set user/password for the main account. We're setting user to admin and password to 123 here
      - SB_USER=admin:123
    # This maps outside folders to inside folders so that your docker container can access them
    volumes:
      # Here we're telling it that the ./data folder should be accessible in the /space folder inside the docker
      # silver bullet stores stuff in the /space folder, so by mapping it to the ./data folder we can keep that data between runs
      - ./data:/space
    # This tells docker to map ports from the inside to your host machine, this allows you to access the docker container as if it were running on your machine
    ports:
      # This tells it to map the internal port 3000 to the external port 5000, so accessing http://localhost:5000/ from your machine will in fact access the same as http://localhost:3000/ inside docker
      # Silver bullet runs on port 3000, so we need to expose that port
      - 5000:3000

Uff, that was a lot, but we’re done, now just run docker compose up -d (up to start -d to run as a daemon, i.e. in the background) and you should be able to access http://localhost:5000/ and get to Silver bullet logging in with admin 123, then if you write about something you will see files appearing in the silverbullet/data folder.

I know that this was a lot in one go, but I chose Silver bullet because it touches all of the most common stuff you’ll need and it’s easy to get going.

Good luck with your self hosting journey, and don’t hesitate to ask if you have any questions.
