In terms of ownership and governance, Red Hat Enterprise Linux (RHEL) is a commercial product developed and maintained by Red Hat Inc., a subsidiary of IBM. In contrast, Rocky Linux is a community-driven, open-source rebuild of RHEL, maintained by the Rocky Enterprise Software Foundation (RESF), which operates independently of Red Hat.
Because Rocky Linux is a third-party rebuild, there is no guarantee that its behavior—especially in complex environments like Quartus Prime—will fully align with that of officially supported RHEL distributions. As such, we strongly recommend using Quartus on a supported RHEL platform to ensure tool stability and avoid unexpected behavior or compatibility issues.
Even if individual bugs are resolved on Rocky Linux, there may be other hidden issues that could emerge over time. These issues will not be supported by Altera, as Rocky Linux is not among the officially supported platforms. For production and critical workflows, we urge customers to use Red Hat Enterprise Linux to ensure full compatibility and access to vendor support.
