Are you sure? If I look at a recent Ubuntu 24.04 build on the main branch, I see that zstd is installed: zstd.zstd_version is logged in "Display build info": https://github.com/python/cpython/actions/runs/15469741916/job/43550824726

It's unclear to me which problem you are trying to solve. Would you mind to elaborate?
