Ubuntu 25.04+ replaced GNU coreutils with uutils coreutils, a Rust-based reimplementation of Unix core utilities. These are different projects with the same package name: - GNU coreutils 9.x (C) - Ubuntu ≤24.04 - uutils coreutils 0.x (Rust) - Ubuntu ≥25.04 The uutils comm doesn't recognize sort output as sorted, causing "comm: file is not in sorted order" errors. Replace comm patterns with: - grep -vxFf for set difference (lines in B but not in A) - sort | uniq -d for finding duplicates These alternatives don't depend on comm, ensuring compatibility with both GNU and uutils coreutils.
