Important Disclaimers and Limitations

Understanding Sober’s experimental nature is crucial before installation. The project remains in active development, meaning users may encounter bugs, crashes, or unexpected behavior during gameplay. Regular updates address stability issues, but complete reliability cannot be guaranteed.

Sober operates as unofficial third-party software, meaning Roblox Corporation doesn’t officially support or endorse its use. While no widespread account bans have been reported, users should understand the theoretical risk of account restrictions.

The closed-source nature of some components means community contributions are limited compared to fully open-source alternatives. Future development depends on maintainer availability and community support.

System Requirements and Compatibility Check

Hardware Requirements

Modern hardware specifications are essential for optimal Sober performance. Your Ubuntu 24.04 LTS system must feature an x86-64 processor with SSE4.2 instruction support. Most Intel processors from 2008 onwards and AMD processors from 2011 onwards meet this requirement.

Graphics capabilities prove equally important. Vulkan 1.0 API support or OpenGL ES 3.0 compatibility ensures proper rendering. NVIDIA users should install proprietary drivers version 418.30 or newer, while AMD users need Mesa 19.0 or later.

Memory requirements start at 4GB RAM minimum, though 8GB provides better multitasking performance. Storage space requirements are modest – approximately 2GB for Sober installation plus 1GB for the Roblox client.

To verify CPU compatibility, execute this terminal command:

grep -o 'sse4_2' /proc/cpuinfo

If the output returns “sse4_2”, your processor supports the required instruction set.

Software Requirements

Ubuntu 24.04 LTS ships with Linux kernel 6.8, which exceeds Sober’s minimum kernel requirement of 5.11. This ensures compatibility without additional kernel updates.

Flatpak serves as Sober’s primary distribution method, making it essential for installation. Ubuntu 24.04 LTS doesn’t include Flatpak by default, requiring manual installation before proceeding with Sober setup.

Desktop environment compatibility extends across GNOME, KDE Plasma, XFCE, and other popular Ubuntu desktop variants. Wayland and X11 display servers both function correctly with Sober, though some users report better performance with X11 configurations.
