What Changed

Linux releases now publish a .deb alongside the AppImage, built from the same electron-builder run by adding deb to the Linux target list (plus the homepage and maintainer metadata the Debian control file requires) and including *.deb in the workflow's collect and publish steps.

Made with gpt-5.6-sol

Why

The AppImage was the only Linux artifact, so anyone who installs through a package manager had no supported path — no desktop entry, no /usr/bin entry, and no dpkg/apt upgrades — and since the .deb reuses the already-staged app, the release gains it without a second build

UI Changes

None

Checklist

  • This PR is small and focused
  • I explained what changed and why
  • I included before/after screenshots for any UI changes
  • I included a video for animation/interaction changes

Note

Low Risk
Changes are limited to Linux packaging metadata, release asset globbing, marketing download links, and tests; no auth, server, or updater behavior changes beyond documenting AppImage-only updates.

Overview
Linux desktop packaging now produces a companion .deb from the same electron-builder run as the AppImage by extending the Linux target list with deb, and setting linux.maintainer plus staged homepage metadata required for Debian control files.

The release workflow collects and publishes *.deb with the other desktop assets. The marketing download page adds a Debian/Ubuntu .deb card, and internal docs describe the new artifact.

In-app auto-updates on Linux remain AppImage-only; .deb installs are manual via dpkg/apt.

Note

Add Linux .deb package to desktop releases

  • Updates build-desktop-artifact.ts to build a deb target alongside the AppImage on Linux, setting DESKTOP_LINUX_MAINTAINER and homepage metadata required for Debian control files.
  • Updates the release workflow to stage and upload *.deb files to GitHub Releases alongside existing artifacts.
  • Adds a Debian/Ubuntu download card to the marketing downloads page pointing to the new .deb artifact.
  • Behavioral Change: Linux AppImage builds now also produce a .deb; the .deb is manual-install only — in-app updates on Linux remain AppImage-only.

Approvability

Verdict: Needs human review

This PR adds a new Linux .deb distribution format to releases, introducing new user-facing download options and modifying the production release pipeline. New features affecting release artifacts warrant human review.

You can customize Macroscope's approvability policy. Learn more.

Linux shipped only the AppImage, leaving users who install through a
package manager without a supported path: no desktop entry, no
/usr/bin entry, and no dpkg/apt upgrades.

electron-builder builds the .deb from the same staged app as the
AppImage, so the release gains a package without a second build. The
AppImage stays the artifact that self-updates in place; .deb installs
upgrade through their package manager instead, which is what the
updater already reports on non-AppImage Linux.

The .deb also needs metadata the AppImage never required: a project
homepage, which electron-builder reads only from the packaged app's
manifest, and an RFC 822 maintainer address for the control file.

The desktop build script already accepts `--target deb`; the target string is
passed through to electron-builder untouched and the artifact copy step is
target-agnostic. A deb build fails only because app-builder-lib's FpmTarget
requires two metadata fields the staged package.json omits: `homepage`
(control "Homepage:") and `maintainer` (control "Maintainer:", otherwise
derived from `author`, which carries no email). AppImage needs neither, so
nothing surfaced this.

Rather than add a second Linux matrix entry -- whose upload artifact name
`desktop-linux-x64` would collide with the AppImage entry's -- let the existing
Linux entry emit both targets from one electron-builder run. `--target` now
takes a comma-separated list, and artifactName's ${ext} already keeps the output
files distinct, so there is one artifact name, one runner, and no collision.

The .deb also has to be listed in the collect step and in both
action-gh-release file lists, or it builds and never ships.

Packages declare Electron's shared-library dependencies per format, so a
minimal Debian/Ubuntu install pulls them in instead of the app failing to
start. The same wiring covers `rpm`, exposed as `dist:desktop:rpm` for local
builds; the release workflow stays AppImage+deb because the runners have no
`rpmbuild`.

Consolidates the overlapping .deb work from pingdotgg#4887, pingdotgg#4900 and pingdotgg#5139: the
dependency lists and the rpm target come from @bigpod98's pingdotgg#5139, the docs and
the download-page card from @benthecarman's pingdotgg#4900.

The .deb is not an updater payload -- in-app updates on Linux stay
AppImage-only, so .deb installs upgrade through dpkg/apt. Documented in
docs/operations/release.md.
t3dotgg added a commit that referenced this pull request Sep 25, 2026
The Linux release build now also makes a .deb in the same electron-builder
run as the AppImage, and the release publishes it. electron-builder lists it
in latest-linux.yml and writes resources/package-type into it, so the app
updates a .deb install through electron-updater, which installs the new .deb
with dpkg. The desktop updater now allows that path.

The .deb uses xz in threaded mode (XZ_DEFAULTS=-T0): 113 MB in place of
141 MB with gzip. The Linux arm64 release job moves to a 16-vCPU Blacksmith
arm64 runner. The download page, README, install guide, and release docs
list the .deb.

Based on community work in #4071, #5139, #4900, and #4887.

in latest-linux.yml and writes resources/package-type into it, so the app
updates a .deb install through electron-updater, which installs the new .deb
with dpkg. The desktop updater now allows that path.

The .deb uses xz in threaded mode (XZ_DEFAULTS=-T0): 113 MB in place of
141 MB with gzip. The Linux arm64 release job moves to a 16-vCPU Blacksmith
arm64 runner. The download page, README, install guide, and release docs
list the .deb.

* fix(sync): resolve wave1 test/build fallout from upstream rebase

After rebase of 78 upstream commits (78 picks, 70 drops) onto c37294d,
the following merge-conflict artefacts remained because the rebase
strategy kept fork-exclusive V2/Pi source while picking upstream
implementations of shared files:

- packages/shared/src/usageMerge.test.ts: removed orphan nested it()
  declaration from commit 9, removed dangling expect+}) from rebase
  residue, and renamed staleEnvironments -> contractMismatches to
  match the upstream field that commit 9/11/13 introduced (the fork
  exclusively uses the contractMismatches field name).
- apps/server/src/usage/usagePricing.ts: collapsed the doubly-nested
  conflict markers left by commits 61 and 75 in cacheSavingsUsd into
  the upstream clause that resolves to rateModel ?? record.model.
- apps/server/src/provider/Drivers/CursorDriver.ts: replaced with the
  upstream main implementation so the file matches the upstream
  auth/modelDiscovery shape; the fork V2 Cursor path was already
  covered by PiAdapterV2.test.ts (61/61 green) and is not touched.
- apps/server/src/provider/Layers/CursorProvider.test.ts: restored
  the fork-main version (252 lines) because the upstream version
  exercises a CursorProvider path that this fork does not implement
  (fork ships only the V2 Pi adapter and the legacy Cursor provider
  layer tests); 7/7 green.
