[Feature] Add steam flatpak support

[kingmaj0r]

Before Requesting

• I found no existing issue matching my feature request
• This request is related to Millennium, and not a request for a specific theme/addon

Describe the feature you'd like!

Could you please add support for Steam Flatpak, as it is currently not supported? I have experience with Linux and would be happy to assist with any Linux-related tasks.

Thank you for considering this request.

Anything else?

I will likely never add millennium to flatpak, or any other unix package manager (and If I do, not in the near future). I already have enough to manage version control for.

they're talking about adding support for the flatpak version OF steam not adding millennium to steam

exactly

Ah, Flatpak support is definitely doable; I must have misunderstood the original question.

No problem, this would also enlarge the support surface as flatpak is distro agnostic! It even fullfills your need to not support every single package distribution repo.

shd any eta on when you can add it? also might I recommend adding a way for someone to specify where their steam is so they can manually make it work

[shdwmtr]

No ETA. There is a lot on the todo list above this.

Its proven to be a lot more difficult then I'd initially anticipated. The way flatpak sandboxes steam is very much so getting in the way. Its messing with some sort of SSL config / the SSL certificates aren't being read from the host, or its using wrong ones, or something else I have no idea.

If anyone interested in the thread wants to work on it themselves, here's how:

1. Install Millennium https://docs.steambrew.app/users/installing#linux

2. Run flatpak override --user --filesystem=$HOME/.millennium:rw This will allow the sandbox to read and write to files in the millennium directory.

3. Replace /var/lib/flatpak/app/com.valvesoftware.Steam/x86_64/stable/active/files/bin/steam with

   #!/usr/bin/python3
   # -*- coding: utf-8 -*-zz
   import re
   import sys
   from steam_wrapper import main
   
   import os
   millennium_py_bin = os.path.expanduser('~/.millennium/ext/data/cache/bin/python3.11')
   
   # if the binary is not executable, make it executable
   if not os.access(millennium_py_bin, os.X_OK):
       os.chmod(millennium_py_bin, 0o755) # 0o755 is the permission mode for user read/write/execute, group and others read/execute
   
   # Preload Millennium shims into the steam runtime
   env_vars = [
       ('LD_PRELOAD', '~/.millennium/libMillennium.so'),
       ('LD_LIBRARY_PATH', '~/.millennium/')
   ]
   
   for var, path in env_vars:
       expanded_path = os.path.expanduser(path)
   
       if var not in os.environ:
           os.environ[var] = expanded_path
       else:
           os.environ[var] += ':' + expanded_path
   
   if __name__ == '__main__':
       print("Starting Steam...")
       sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
       sys.exit(main())

4. Run steam flatpak run --branch=stable --arch=x86_64 com.valvesoftware.Steam

5. Atleast for me, while Millennium is bootstrapping it crashes on an SSL error
   ssl.SSLError: unknown error (_ssl.c:3098)
