Selfhosted

Mint or Ubuntu is like Windows but better.

If you are mostly hosting files, open media vault has minimal command line, and it's mostly administered through a web admin. It's still fairly complex however, and I definitely recommend reading the manual thoroughly and sticking with easy tasks at first. https://www.openmediavault.org/

Hey :) I'm not giving you any recommendations but want to give you my personal experience !

5 years ago I had absolutely no clue about Linux/CLI/networking/docker... You name it ! And I also wanted to repurposed and old laptop as a server.

The first distro I installed on my server was Debian ! Why? Because I remembered my brother said something along the line: "Every server infrastructure is run by Debian or a Debian derivative". So this sounded like the perfect thing to install as a server distro :) !

5 years later I'm still running Debian on this old laptop and it's going strong ! Never did it failed me except if I did something wrong over the CLI !

As you guessed it, you will need some degree of proficiency on the command line specially if you install your distro without a graphical user interface, which I would recommend... Yes, the CLI isn't easy to beginning with and you will do some mistakes that will need a full reinstall of your system... But before you learn to move, you learn to stay up right on your legs and this involves a lot a failing !!

It's not mandatory, you can install a lightweight GUI and take your time. There are a lot of application with good UI which will help you out ! However, not once did I regret to take the harder route and learned so many things along the way ! After this amount of time in the CLI, I can say I'm getting quite good In navigating my system, keeping it healthy and alive :p !

Okay, If it's a matter of time I get it ! We only have 24h a day and most of this time is already spend at work/school, family time, friends, sleep, eat ! If you're lucky enough to have 2 hours to spare to tinker arround, a UI is a good idea to keep a healthy balance between all your personal activities ! But keep in mind, both are thorny and have their fair share of issues and debug time.

Last words, have fun with your system :)

Not that I'm using them, but what about these two?

I honestly would use a headless Linux system with docker compose. You can find premade docker compose files.

I'm not trying to be unhelpful. My advice would be to steer into the terminal. Bite the bullet. I use arch and alpine for my servers but Fedora would be fine (but SELinux can be a pain with bund mounts)

Probably just go with Fedora with btrfs for snaps. It has lots of support and is a common choice for servers

i tried CasaOS for a quick minute. its decent and just has the basics like setting up any disks and then has an app store. its really just a front end for docker and you can manually input the details of any docker containers that arent in the store

ive mostly been running docker stuff on my Synology nas. cant think of the model number now, 218+ i think, but any of the "plus" models will let you run docker. its very similar to Casa, no messing around with command line stuff. ive been self hosting for 10 years now and never touched the command line so i dont know what people are on about here saying you will have trouble

dietpi is another thing ive used on a few devices, mainly small SBCs and raspberry pi's, but i think they might have a version that you can install on anything. its basically just debian, and it has a sort of a wizard that helps set up various things like set up disks and install apps. its headless though so no GUI unless you install one, and the wizard is run from the terminal but youre not having to type any commands at least

I went with Truenas Scale and was pleasantly surprised it needed no command line kung fu

FWIW I've been using Ubuntu desktop with CasaOS for a couple of months now to host Nextcloud, Jellfin, Immich and a few other bits and bobs with absolutely no issues at all so far!

(I’m not very good with the command line)

Me either so I take a lot of notes about commands and command sequences. Also, I find that Grok is pretty decent at explaining commands. AI is a wonderful tool, but you also need to do your due diligence in ascertaining whether AI has given you the correct information. I would not copy/paste random commands into a production server, but rather I have a small test server for that kind of stuff. Once I have the command, tested, and understand the command, I can then use that in a production environment.

In as much as I love a good WUI, you will have to learn some cli, it's just inevitable, especially in a headless environment. It may seem daunting at first because there are literally thousands of commands and command sequences. I honestly doubt if even the geekiest nerds on the planet know all by heart. For each command sequence, there are probably hundreds of ways to compose the same command. I would admonish you to download Notepad ++ and start keeping notes on the commands you use. Later on, the fun part is looking back on your notes to see all the commands you now know and what they do.

Core utilities (like ls, cd, cat, etc.) from projects like GNU Coreutils provide around 100-200 commands. Additional tools from packages (e.g., grep, awk, sed) and system utilities (e.g., systemctl, iptables) can add hundreds more. On a system with many packages installed, running compgen -c | sort -u | wc -l in a Bash shell might show 2,000–10,000+ unique commands, depending on the setup.
