Linux currently ships a single AppImage. Two reasons to also ship native packages:

AppImages carry a lot of bloat. They bundle their own copy of GTK, WebKit and every supporting library so they can run anywhere, and the user pays for that on every download and on disk. Measured on this change: the AppImage is ~120 MB while the same app as a .deb or .rpm is ~55 MB — less than half, for identical functionality. The distro already ships those libraries; the AppImage just refuses to use them.

Many users prefer their platform's own packaging. apt install / dnf install gives them the system's install, upgrade and removal path, a properly registered desktop entry, and no FUSE dependency — instead of a loose executable they have to chmod +x, place somewhere sensible, and update by hand. For plenty of people that's the difference between installing the app and not bothering.

This adds .deb and .rpm, built by the same tauri build run.

This is a policy change, not a bug fix. The single-target limit was deliberate and pinned by a test whose message says so:

"Linux ships a single AppImage; adding targets here multiplies release assets"

So it's entirely reasonable to say no. I've rewritten that test rather than deleting it — the target list stays an explicit set, with a message pointing at the three places that must change together (build, payload verification, publish asset list).

Sizes

Asset Size
TokenTracker-linux-x86_64.AppImage ~120 MB
TokenTracker-linux-x86_64.deb ~55 MB
TokenTracker-linux-x86_64.rpm ~55 MB

The trade-off: the packages depend on the distro shipping a compatible webkit2gtk-4.1, where the AppImage carries its own. That's exactly why this is additive — the AppImage stays for anyone who needs the self-contained version.

Payload verification

The existing check extracted the AppImage and failed if EmbeddedServer/node was missing — the thing that catches a broken bundle.resources mapping before it reaches users. Each format is produced by a separate tauri bundler and can fail independently, so that check now runs against all three rather than treating the AppImage as a proxy. It's factored into one verify_payload function asserting the same things it always did: the binary, a complete EmbeddedServer (tracker.js, package.json, dashboard/dist/index.html), and an executable node.

rpm2cpio and cpio are not on ubuntu-latest by default, so the rpm arm installs them; the test asserts that, since without them the rpm could never be inspected.

Verified locally

Built and unpacked both packages rather than assuming:

  • Both install the runtime at /usr/lib/TokenTracker/EmbeddedServer/node, which candidate_runtime_roots already probes via <prefix>/lib/<PRODUCT_DIR_NAME> — so a packaged install resolves its runtime with no code change
  • node is executable in both; all three required EmbeddedServer files present
  • I extracted the workflow's verification script and ran it against the real bundles, then rebuilt a .deb with EmbeddedServer stripped and confirmed it fails with a non-zero exit — the check is not decorative
  • Removing the rpm/cpio apt deps fails the workflow test

The AppImage arm could not be exercised on my machine (linuxdeploy needs FUSE, which CI installs) — that arm is unchanged apart from being moved into the shared function, but CI is the authority on it.

One caveat worth your call

Tauri hardcodes libappindicator3-1 as the deb dependency. That package exists in Ubuntu 24.04 (universe) but not Debian 12, so the .deb won't install there. bundle.linux.deb.depends only appends to Tauri's defaults — I tried overriding it and it produced duplicate entries while leaving the original in place — so it can't be fixed from config. Documented in the README (Debian users are pointed at the AppImage). If you want it properly fixed, it needs a repack step in CI or a fix upstream in Tauri; happy to add the former if you'd prefer.

The Arch PKGBUILD is untouched and stays a local-build path.

Summary by CodeRabbit

  • New Features

    • Added Linux release packages in AppImage, DEB, and RPM formats.
    • AppImage bundles GTK/WebKit dependencies and requires only a recent glibc.
    • DEB and RPM packages support Debian/Ubuntu and Fedora/RHEL installations.
    • Added guidance for Debian 12 users to choose the AppImage instead of the DEB package.
  • Documentation

    • Updated installation instructions across supported languages with package options, commands, and dependency details.
  • Tests

    • Added validation for all Linux package formats and release assets.

Linux shipped one AppImage, so apt and dnf users had to fall back to a
FUSE-dependent binary with no package manager integration. Add native
packages for both, built by the same tauri run.

The single-target limit was deliberate and pinned by a test, so that test
is rewritten rather than deleted: the target list stays an explicit set,
because every entry becomes a release asset the publish job's
required-asset check must also list.

Each format is produced by a separate tauri bundler and can fail on its
own, so the payload verification now runs against all three rather than
trusting the AppImage as a proxy. It is factored into one function and
checks what it always checked -- the binary, a complete EmbeddedServer,
and an executable node -- against an extracted tree per format. rpm2cpio
and cpio are not on ubuntu-latest by default and are installed for the
rpm arm.

Verified locally by building and unpacking both packages: each installs
its runtime at /usr/lib/TokenTracker/EmbeddedServer/node, which
candidate_runtime_roots already probes, so the app resolves its runtime
from a packaged install with no code change. Stripping EmbeddedServer
from a rebuilt .deb makes the verification fail, so the check is not
decorative.

Both packages are roughly 55MB against the AppImage's 120MB: they link
the system GTK/WebKit instead of bundling it, which is also why they
depend on the distro shipping a compatible webkit2gtk-4.1.

I reviewed exact head 4b42b615f4160186ae41df2d2a16ee476b8f9b87. The package verification is thorough, but this changes the release contract from one Linux AppImage / four total assets to AppImage + deb + rpm / six total assets without updating the repository source of truth.

CLAUDE.md still explicitly requires a single AppImage and exactly four release assets, and the release/read-back procedure is defined from that contract. Please update CLAUDE.md and all aligned release documentation/tests in the same PR, including the expected asset inventory and verification steps, so maintainers and automation do not enforce contradictory policies. Then rerun the combined release workflow tests.

Conclusion: NO-MERGE until the canonical release contract is updated.

Publishing .deb and .rpm left CLAUDE.md describing a Linux job that builds
a single AppImage and a publish job that verifies four assets, so the
canonical contract contradicted the workflow it documents. Update it to
three Linux packages and six assets, and add an explicit asset inventory
table: the publish job's required-asset check is the thing that refuses to
flip the draft live, so the list maintainers read should be the same list,
alongside the note that changing it means touching the workflow and
test/linux-client-workflow.test.js together.

The Linux README's distribution list had ended up with two overlapping
AppImage bullets and an Install section that jumped straight into the
AppImage with no heading, leaving the new apt and dnf sections dangling
under it. Restructure into one release-packages bullet and three parallel
subsections.

Correct the dependency claims while here. Every README said the AppImage
needs webkit2gtk-4.1, gtk3 and libayatana-appindicator from the distro,
which the build tree disproves: the AppDir carries libwebkit2gtk-4.1,
libjavascriptcoregtk-4.1, libgtk-3, libappindicator3 and the
WebKitWebProcess / WebKitNetworkProcess helpers, and AppRun prepends
$APPDIR/usr/lib and usr/lib64 to LD_LIBRARY_PATH so those copies are what
load. The system stack is what the packages need instead -- the .deb
declares libwebkit2gtk-4.1-0, libgtk-3-0, libayatana-appindicator3-1 and
libappindicator3-1, the .rpm the equivalent sonames -- which is also why
they are 55MB against the AppImage's 120MB, and why the .deb is
uninstallable on Debian 12. librsvg is dropped from the runtime lists: it
is a build dependency, and nothing named rsvg is in the AppDir.

Fixed in 14bbd3d. You're right that the contract was left contradicting the workflow — thanks for catching it.

CLAUDE.md

  • The linux job no longer "builds a single AppImage": it builds all three packages from one tauri build, and the payload verification is described as per-format, since each format comes from its own bundler and can fail alone.
  • "verifies all four assets" → six.
  • Added an explicit Release asset inventory table (dmg / win zip + installer / AppImage + deb + rpm), with the rule that changing the list means touching the workflow's upload and required-asset steps and test/linux-client-workflow.test.js together. The publish job's required-asset check is what actually refuses to flip the draft live, so the list maintainers read is now the same list.
  • Step 3 and the embedded-runtime paragraph updated to match.

Aligned docs

  • TokenTrackerLinux/README.md: the earlier commit had left two overlapping AppImage bullets and an ## Install section that jumped straight into the AppImage with no heading, so the new apt/dnf sections dangled under it. Restructured into one release-packages bullet and three parallel subsections.
  • README.md + the four translations: .deb/.rpm install paths added.
  • .github/workflows/ci.yml: the comment explaining why bundling is left to the release workflow now names all three formats and the rpm tooling.

Tests — the two that pinned the old contract were already rewritten rather than deleted in 4b42b61 (bundle_produces_the_three_supported_linux_targets keeps the target set explicit; the publish test now asserts all six assets). Reran on the new head:

  • node --test over linux-client-workflow, release-dmg-workflow, release-windows-workflow, npm-publish-workflow, linux-bundle72 pass, 0 fail.
  • cargo test --test capabilities9 pass, 0 fail.
  • Full npm test — 2423 pass, 5 skipped. One file, test/legacy-baseurl-migration.test.js, intermittently dies with the node test-runner's Unable to deserialize cloned data IPC error; it passes 14/14 run alone, and this commit is docs-only.

One correction that came out of this. Every README claimed the AppImage "needs webkit2gtk-4.1, gtk3 and libayatana-appindicator from your distro". The build tree says otherwise: TokenTracker.AppDir/usr/lib carries libwebkit2gtk-4.1.so.0, libjavascriptcoregtk-4.1.so.0, libgtk-3.so.0 and libappindicator3.so.1, plus the WebKitWebProcess / WebKitNetworkProcess helpers in usr/libexec, and AppRun prepends $APPDIR/usr/lib and usr/lib64 to LD_LIBRARY_PATH, so those copies are what load. The system stack is what the packages need — the .deb declares libwebkit2gtk-4.1-0, libgtk-3-0, libayatana-appindicator3-1, libappindicator3-1 and the .rpm the equivalent sonames — which is also the 55MB vs 120MB gap, and why the .deb is uninstallable on Debian 12. librsvg is dropped from the runtime lists: it's a build dependency, and nothing named rsvg is in the AppDir.

The asset inventory said `publish` refuses a draft that does not carry
exactly six assets. It loops over the six names and fails on a missing
one; extras are never inspected. Say what the check does rather than
describing a stricter gate that is not there.

The release step put "(all in parallel)" next to "the three Linux
packages", which reads as the packages building concurrently. One
`tauri build` runs three bundlers in sequence; what is parallel is the
three platform jobs.

The .deb declares both libayatana-appindicator3-1 and libappindicator3-1,
and Debian 12 dropped the latter in favour of the former, so apt refuses
the package there. TokenTrackerLinux/README.md already said so; the
install docs users actually reach did not. Added to README.md in both
places that offer the .deb, and to all four translations rather than only
the two flagged -- the rest carry the same .deb line and would otherwise
keep promising an install that fails.

The CLAUDE.md correction is right and the per-format payload verification is the part I'd have asked for. One change before I merge.

pick_one writes its error to stdout, which is captured. It's only ever called inside a command substitution, so the ::error:: line lands in $image / $deb / $rpm_pkg instead of the log. I ran it:

image="$(pick_one AppImage /nonexistent/*.AppImage)"
→ exit 1, stdout empty, stderr empty

The failure itself is correct — set -e still aborts the step, because the assignment isn't local and so doesn't mask the substitution's status. But the job dies with no line saying why, in the one workflow where a silent failure is most expensive: the draft is already created, two other platforms have uploaded, and whoever picks it up sees a red step with no message. Send it to >&2.

While you're there, verify_payload's errors are fine as-is — it isn't called in a substitution, so those reach the log.

Not a blocker, just noting the risk we're both accepting. Nothing in CI exercises the deb/rpm bundlers or the extraction path; linux-client-workflow.test.js asserts the YAML, not the build. First real proof is a dispatch. The failure mode is safe — a bundler failure leaves the release unpublished rather than half-public — but it will block a release when it happens, so I'll dispatch this on the next version rather than a hotfix.

Push the stderr fix and I'll merge.

pick_one is only ever called inside a command substitution, so its
::error:: line landed in $image / $deb / $rpm_pkg instead of the
workflow log. The step still failed under set -e, but silently -- in the
one workflow where that costs the most, with the draft already created
and two platforms uploaded.
