fix(update): stop offering a Linux app update that is never built

[gigara]

Problem

A publishing release cannot complete. publish-update-source fails in generate-update-manifest.mjs before it writes anything.

build_linux defaults to true in build.yml, release.yml and dev-build.yml, and is hardcoded true in daily-build.yml, so linux-x64 always lands in the published targets. The manifest config then asks for an installer that nothing builds:

"linux-x64": "wso2-integrator_{version}_amd64-update.deb"

Windows builds an editor-only installer alongside the full one (INSTALLER_PROFILE=editor-update → wso2-integrator-<v>-update.msi, build.yml:1306-1310) and macOS has its Squirrel payload, but Linux only ever gets the full .deb from compile.yml. The assets on v5.0.0 show it — wso2-integrator_5.0.0_amd64.deb, with no -update variant.

The generator has to download each app installer to compute its sha256 and mirror the bytes, so this isn't a dangling URL in the output — it's a 404 that throws and fails the job.

Loud rather than silent, which is the right direction, but it blocks every release that publishes updates. Daily and dev builds are unaffected: they set build_linux: true but never publish.

Change

Drop the linux-x64 entry from app.installers. That's sufficient on its own — the app loop skips a target with no installer name:

const installerName = installerNames[target];
if (!installerName) {
  continue; // no core-app installer published for this target
}

linux-x64 deliberately stays in targets and platformTokens. compile.yml runs update-product.sh, so the Linux .deb/.rpm carry the update endpoint and pinned key and do poll the server. Their component artifacts — the Ballerina distribution, the JRE, the extension VSIXs — all exist upstream and mirror fine. Only the core-app update is unavailable, so Linux clients keep getting component updates and are simply never offered an app update.

Removing linux-x64 from targets instead would have traded one hard failure for another: the workflow still passes it in --targets, and the generator rejects targets missing from config.targets.

Verification

Structure-only run with all four targets requested:

node ci/build/generate-update-manifest.mjs \
  --targets darwin-arm64,darwin-x64,win32-x64,linux-x64 \
  --sequence 1 --app-version 5.1.0 \
  --app-release-base .../releases/download/v5.1.0 \
  --artifacts-base https://updates.wso2.com/artifacts \
  --no-download --out src.json

Wrote src.json (9 components x 4 targets, 1 app entries)
  app 5.1.0 targets: darwin-arm64, darwin-x64, win32-x64
  components carrying linux-x64: 9 of 9
  any linux app installer: false

No attempt to resolve a Linux .deb, all nine components still cover linux-x64.

Restoring it

One line, once an editor-update .deb is built the way Windows builds its MSI.

Walkthrough

The installer manifest removes the linux-x64 mapping for the AMD64 Debian package. The manifest retains the darwin-arm64, darwin-x64, and win32-x64 mappings.
