I could reproduce locally and find the issue. This is a really major break in the `env` program: it doesn't re-execute with the subcommand, instead it forks! So then terminating the env process keeps the subcommand running. This affects all scripts whose shebang uses /usr/bin/env.
Think of any systemd-managed python daemon; now stopping the service doesn't terminate the daemon if its shebang looks like `#!/usr/bin/env python3`. ** Changed in: coreutils-from (Ubuntu) Status: New => Triaged ** Changed in: pipewire (Ubuntu) Status: New => Invalid ** Changed in: mutter (Ubuntu) Status: In Progress => Invalid ** Changed in: rust-coreutils (Ubuntu) Status: New => Triaged ** Changed in: rust-coreutils (Ubuntu) Importance: Undecided => Critical ** Changed in: rust-coreutils (Ubuntu) Milestone: None => ubuntu-25.10 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2112491 Title: mutter & gnome-shell: FTBFS with coreutils-from: pipewire stuck in an accept4 loop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/coreutils-from/+bug/2112491/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
