SteamOS Utils fails to enable acpi_call on SteamOS 3.8.14 (kernel 6.16.12-valve24.4-1-neptune-616)

[lmichal2011]

Environment

• Device: Lenovo Legion Go (original)
• OS: Official SteamOS
• SteamOS version: 3.8.14
• Kernel: 6.16.12-valve24.4-1-neptune-616
• SteamOS Utils: Latest version from GitHub

Description

Running:

./SteamOSUtils.py --enable_acpi_calls

fails because the script tries to download the required kernel packages from Valve's servers, but the request returns:

HTTP Error 404: Not Found

After that, the script crashes with:

TypeError: not enough arguments for format string

Expected behavior

The tool should either:

• download the correct packages for SteamOS 3.8.14 / kernel 6.16.12-valve24.4-1-neptune-616, or
• fail gracefully with a clear error message instead of crashing.

Additional information

This was reproduced on an original Lenovo Legion Go running the latest official SteamOS 3.8.14.

It appears that either the download URL is outdated (HTTP 404) or the latest SteamOS kernel is not yet supported. Additionally, the exception handler itself crashes with a formatting error (TypeError), which makes troubleshooting more difficult.

If needed, I can provide the full terminal output.

Thank you for your work on this project!
