How is everyone installing Lemmy?

I have tried installing it with docker on Ubuntu 20.04 and 22.04 LTS but cannot seem to get it working. The build keeps erroring out with docker errors.

If your using docker I recommend getting a docker-compose file that does 98% of the config work for you. Pretty sure there's one in the install docs.
- I've been having trouble understanding how the docker-compose thing works, and the whole... impermanence of docker containers. Got any tutorials you'd recommend? Note I'm on Windows.
  
  Are you planning to host it on a Windows machine?
  
  If you don't have experience with docker, don't jump straight to docker compose. Start simpler.
  
  If you want to have data persist after a container is killed, have a look at the -v option of "docker run". It allows you to mount a volume.
I used Lemmy Easy Deploy
What are the errors?
If you post your configs and errors we might be able to help you. I set up a vm with docker compose and proxy it through traefik instead of nginx
You are using two technologies that have a bad of working like shit, together; Ubuntu/snap and docker. You can try podman if you want, or a different distro. Or, at least, install the official docker way.
Post your docker-compose file and error message here so people can actually provide advises for your setup.
I had some luck with the prebuilt images from dessalines' dockerhub and using the compose file in the repo with logging commented out.

It was stable for about a week before I tried to update and broke my database and federation completely. I might try again when 0.18 stable drops.
- another docker user here. Why does our thumbnails look the same :) I know there is something wrong with my setup. I made a post here https://leddit.minnal.icu/post/1045 but still no idea.
- always make a database backup before performing upgrade.
I was able to get it running from source on Gentoo (without docker). Building from source is an option but you need to manage the dependencies and daemons yourself. This is my first comment! Good luck with your setup
Will self-hosting Lenny have the limitation that you’ll be missing a lot of comments when subscribing to magazines from other instances? I am considering it tough
The Ansible method is easy and worked fine for me on 22.04: https://github.com/LemmyNet/lemmy-ansible

Just remember to setup ssh without a password using this command from your local machine:

ssh-copy-id yourserver.com
I've been having issues with 0.17.4. I saw people suggesting a non-docker, build from git method but really wanted docker to work.

I'm now using 0.18.0-rc.4. Built without issue using the dockerhub image and has been stable for 24hrs
I've been trying for more than a week. LemmyEasyDeploy worked. But now i'm stuck with ssl certificate.
- Lemmy Easy Deploy handles the SSL certificates for you. You don't need to buy them
  
  I get ssl errors when i try to access the site.
I got mine running via Docker by copying the docker-compose, nginx, and lemmy.hjson files from the lemmy-ansible repo. Everything is working so far except votes and comments from other instances. They won't sync for some reason.
- Here is mine https://gist.github.com/jeena/6179470a8d616455f30635a5c71f5f64 which had a similar problem with the comments, although I couldn't post comments on my own instance either.
  
  For me the thing was that I had to add:
  
  map $http_upgrade $connection_upgrade { default upgrade; '' close; }
  
  and
  
  proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $connection_upgrade;
  
  And also change the nginx in the docker to port 8080 so my normal nginx could keep running on 80 and handle all the ssl certificate stuff.
  
  My setup is:
  
  Browser -> native Nginx -> docker Nginx -> lemmy
