Does anyone have any guides or knowledge about reformatting a Linux based OS system and setting up mise and not Asdf.
Why do you want to reformat? What do you even mean with that?
Can you give some more context on what your actual problem is?
Any Linux Distros website gives instructions for the installation of linux part.
For setting up mise you should check the mise website.
Anyway, seeing you asking all these questions, I do not think you should go through this alone, you should do a backup of all important data, and find someone who walks you through this and explains you how to use the software you install together.

If you look at my other posts of trying to figure out why openssl won’t work and apparently my tool manager is out of date and I have to try to update it and it might be the right thing to have a fresh start.
The fact that your openssl version does not match what a prebuilt OTP from years before the release of your linux distro expects, is unrelated to your tool manager. I have explained that also in one of the many other threads.

I understand that, So what are my options then trying to update my tool manager, Reformatting my PC and what else.
At this point, I seriously suggest you to start using an AI agent. You are using this forum as one anyway. The thing is, human are terrible at helping you this way because we are highly opinionated, will easily lose patient, and may use whatever you said against you.

LLMs don’t have opinions, though they will hallucinate facts.
LLMs won’t be impatient, though they will happily lead you into bricking your system and then when you tell them, smile in your face and will say “sorry”…
I am still the opinion, they should find a personal mentor, idially in person and on site, who sits down for at least a day and sets up the PC with them for them.
If there weren’t thousands of kilometers of distance between us I would even offer myself.

I believe that we could make it work, There are ways of us to have video calls and figure this issue out.
Video calls are not what I call “in-person” and “on-site”. And ~7h of TZ difference is also not viable for me and my family to do this.
As said, there are thousands of kilometers between us.
That sucks so I will look back at your advice and start from the beginning and try to figure this out
I have no truly important things on this computer, I could reformat it and start from scratch with mise as I’ll look into that, I have to re read these threads again and try to see if I can find the solution.
You have at least this project that you are trying to get to run desperately. And from your past messages, it is not clear whether it was given to you with that computer or whether you got it from somewhere else, or whether is is even publicly available.

Personally if I was given a computer and there’s nothing on it I want/need I would want to reformat it (wipe everything and then reinstall the OS) just so I’m confident it’s a clean working system.
However it is a bit out of scope for this forum so you may want to:
-
Go on to the Ubuntu forum, explain what machine and spec you have, tell them what issues you are facing and asking them for advice on whether it is worth reformatting and if so to help guide you. (One thing they might suggest is booting Ubuntu from an external disk to check the machine is compatible, and only if it is to proceed with a format/wipe. You could also do that and try installing an Elixir dev env on that - that way you’ll essentially have two systems to experiment with.)
-
Once you have a clean machine then install your dev environment.
Caveat: I am not a Linux home-user, so I cannot say how easy/difficult it would be. Doing a reformat on a Mac is easy enough, as it is on a Linux production system, but I have no idea what challenges you might face with Ubuntu for home use on your particular machine, hence I recommend getting help from the Ubuntu community directly.
Alternatively you may want to try and fix your current system by following some set-up guides for your OS. If you do that, and need more help, please provide more information - what you tried, what you’ve managed to do/not do, what’s working/not working etc. Please include as much info as possible and please do not start any new threads related to this topic (just use this one). Thank you and good luck

Yeah that’s the right thing to do. Mainstream Linux distros have come a very long way and the live disks are polished and useful by themselves.

Here’s everything you need:
# Install Mise
curl https://mise.run | sh
# Activate Mise to keep the environment variable and `PATH` updated automatically.
echo 'eval "$(~/.local/bin/mise activate bash)"' >> ~/.bashrc
# Restart current shell session
exec bash -l
# Install Erlang
mise install erlang@latest && mise use erlang@latest
# Install Elixir
mise install elixir@latest && mise use elixir@latest
# Run Mise Doctor to verfiy no issues
mise doctor
# List installed tools & runtimes
mise ls
