+# Linux arm64 build notes
+
+This note documents the current local path for building a Linux arm64 package for Rubick.
+It is intended for maintainers and users who want to test an arm64 Debian package before an official release is published.
+
+## Supported target
+
+- The current Electron Builder configuration in `vue.config.js` defines the Linux package target as `deb`.
+- The Linux icon directory is `public/icons/` and the package product name is `rubick`.
+- The project uses Electron `26.0.0`, Electron Builder, and Vue CLI Electron Builder.
+- The repository pins Node.js `16.20.2` in the `volta` section of `package.json`.
+- Building on a native arm64 Linux host is the safest option because native dependencies are installed for the host architecture.
+- Cross-building from x64 Linux may require extra Electron Builder and system configuration that is outside the default project setup.
+
+## Prerequisites
+
+- Use Linux arm64/aarch64 for the machine or container that runs the package build.
+- Use Node.js `16.20.2` when possible; Volta can install the pinned version automatically.
+- Use the npm version resolved by the project lockfile and scripts instead of mixing package managers.
+- Install standard Debian packaging helpers such as `dpkg`, `fakeroot`, and `rpm` if Electron Builder reports missing tools.
+- Install build essentials such as `python3`, `make`, and `g++` so native Node modules can rebuild.
+- Ensure Git subdirectories are clean before packaging because Electron Builder copies the app output into the final artifact.
+
+## Commands
+
+```bash
+npm install
+npm run postinstall
+npm run electron:build -- --linux deb --arm64
+```
+
+If the build environment already runs on arm64, Electron Builder may also infer the host architecture:
+
+```bash
+npm run electron:build -- --linux deb
+```
+
+## Expected artifact
+
+- The default Linux output is a Debian package because `vue.config.js` sets `linux.target` to `deb`.
+- The generated file is written under the Electron Builder output directory, commonly `dist_electron/`.
+- The artifact name is controlled by Electron Builder when no Linux-specific `artifactName` is set.
+- Check the build log for the exact `.deb` path and architecture suffix.
+- For issue triage, include the package filename, host architecture from `uname -m`, and Node version from `node -v`.
+
+## Native dependency notes
+
+- `uiohook-napi` and clipboard-related packages may need architecture-specific native binaries or a local rebuild.
+- If `npm install` fails on a native module, remove `node_modules` and reinstall on the same arm64 host used for packaging.
+- Run `npm run postinstall` after dependency changes so `electron-builder install-app-deps` can rebuild Electron native modules.
+- Avoid copying `node_modules` from an x64 machine into an arm64 build environment.
+
+## Troubleshooting
+
+- If Electron download fails, configure the Electron mirror used by your network and retry `npm install`.
+- If the build fails with a missing system package, install the package named in the Electron Builder error and rerun the same command.
+- If the resulting package installs but the app does not start, run it from a terminal and attach the native module error to the issue.
+- If the artifact architecture is not arm64, confirm the build command includes `--arm64` or that the host is actually `aarch64`.
+- If cross-building is required, document the host distribution and Electron Builder version because results can vary by distro.
