The Linux t3 binary does not start on a fresh Ubuntu 24.04 server, so the first npx t3 up (or install.sh) a new user runs fails:

t3: error while loading shared libraries: libatomic.so.1: cannot open shared object file: No such file or directory

Node's Linux runtime links libatomic.so.1, and Ubuntu server, cloud, and container images do not ship libatomic1.

Fix

The Linux CLI archive now ships its own copy at lib/libatomic.so.1, and the build sets the t3 RUNPATH to $ORIGIN/lib with patchelf. Nothing to install, no extra step.

Why this option:

• One fix for every launch path. install.sh, npx t3, the t3 up service (~/.t3/runtime/versions/<v>/t3), SSH tunnel installs, and WSL installs all extract the whole archive, so lib/ sits beside the binary. $ORIGIN resolves through the ~/.local/bin/t3 symlink. An LD_LIBRARY_PATH launcher would need changes in each of those places and would leak into agent shells.
• Not fragile across glibc distros. libatomic.so.1 needs only glibc 2.14 symbols. Node already needs 2.28. Checked on rockylinux:8, debian:11, ubuntu:22.04, fedora:43, and archlinux.
• A check-and-print-the-command fix (option 1, as in fix(cli): the Linux installer names the missing libatomic package instead of a generic failure #22909) still leaves a manual step. A SEA without libatomic (option 3) would mean building our own Node.

Changes:

• scripts/build-cli-archive.ts: on Linux, find libatomic with ldd, copy it to lib/, and set RUNPATH. The arm64 64 KiB page check now runs on the patched binary. libatomic is GPL-3.0-or-later WITH GCC-exception-3.1, so the archive also ships lib/libatomic.so.1.LICENSE: the exact Ubuntu package and version, its Launchpad source link, the package copyright file, and GPL-3.
• scripts/smoke-cli-archive.ts: on Linux, require lib/libatomic.so.1 and its notice, and fail unless ldd resolves libatomic to the archive copy. The runner has libatomic installed, so --version alone would not catch a regression. This check fails on the v0.1.4 archive.
• release-desktop.yml: install patchelf before the archive build (the apt mirror setup moves up to run first).

With this merged, #22909 (installer hint for the same error) is no longer needed.

Before and after

Clean ubuntu:24.04 container, install.sh against a local release server. Before is the published v0.1.4 archive. After is an archive built from this branch.

Before:

+ ls /usr/lib/x86_64-linux-gnu/libatomic*
ls: cannot access '/usr/lib/x86_64-linux-gnu/libatomic*': No such file or directory
+ T3CODE_VERSION=0.1.4 sh install.sh
  Installing T3 Code 0.1.4
  Extracting T3 Code...
/root/.t3/runtime/versions/.staging-cPdrK1/t3: error while loading shared libraries: libatomic.so.1: cannot open shared object file: No such file or directory
t3 install: the downloaded executable does not run

After:

+ ls /usr/lib/x86_64-linux-gnu/libatomic*
ls: cannot access '/usr/lib/x86_64-linux-gnu/libatomic*': No such file or directory
+ T3CODE_VERSION=0.0.0-libatomic sh install.sh
  Installing T3 Code 0.0.0-libatomic
  Extracting T3 Code...
  Setting up the t3 command...
  Installed T3 Code 0.0.0-libatomic
+ t3 --version
t3 v0.1.4
+ start the server from the installed runtime, then curl it
HTTP 200 from t3 serve

arm64 (qemu, ubuntu:24.04): the v0.1.4 binary fails with the same loader error. The same binary patched with patchelf --set-rpath '$ORIGIN/lib' and Ubuntu's arm64 libatomic in lib/ prints t3 v0.1.4 and passes assertLinuxArm64PageCompatibility. I could not build an arm64 SEA on this x64 host, so the release job's arm64 smoke step is the first full arm64 build.

I did not run t3 up inside a container (no systemd). The service starts the same extracted ~/.t3/runtime/versions/<v>/t3, which the run above covers.

vp run check:changed passes. Smoke script passes on the new archive, including with a symlinked or space-containing TMPDIR.

Proof: reproduced the loader failure on clean ubuntu:24.04, then installed and ran an archive built from this branch on the same image.

Approvability

Verdict: Approved at f4f2bcc

Macroscope's review found this PR approvable — Linux CLI archives now include libatomic so fresh Ubuntu installations can start without installing it separately. The dependency stays local to the archive, with license information and checks that the executable loads the bundled copy.

Walkthrough

The Linux CLI archive build now bundles libatomic.so.1, sets the staged executable’s RUNPATH, and checks ARM64 page compatibility on the staged executable. The Linux archive smoke test verifies the bundled library and its license file.

Changes: Linux CLI archive

Layer / File(s)	Summary
Prepare and stage the Linux CLI archive .github/workflows/release-desktop.yml, scripts/build-cli-archive.ts	The workflow sets up apt mirrors before CLI archive packaging and installs patchelf when needed. The build bundles libatomic.so.1, writes its license and source-reference information, sets the executable’s RUNPATH, and checks ARM64 page compatibility on the staged executable.
Verify the bundled library scripts/smoke-cli-archive.ts	The Linux smoke test requires lib/libatomic.so.1 and its license file. It fails if ldd does not resolve the executable’s library to the bundled copy.
