+## 3. Repository Issues
+
+### Issue #1 — Ubuntu 26.04 issue (OPEN)
+
+**URL:** `https://github.com/opensnap/antigravity/issues/1`
+**Reporter:** Mike20242
+**Date:** 2026-07-25
+**Labels:** (none)
+**Assignees:** (none)
+
+#### Description
+
+```
+Tried running the install command on latest Ubuntu version (Resolute Raccoon)
+and it shows these errors:
+Could not find official Antigravity 2.0 tarball for linux-x64 in Google download bundle
+bash: line 1: tmpdir: unbound variable
+How do I fix it?
+```
+
+#### 2 Bugs Reported
+
+**Bug 1: Download URL Resolution Fails**
+- Message: `Could not find official Antigravity 2.0 tarball for linux-x64 in Google download bundle`
+- Cause: The `install.sh` script searches for a JavaScript file `main-*.js` on Google's download page, then scrapes the tarball URL from inside that JS bundle.
+- Reality: Google has rebuilt the download page using the **Astro framework**. Download links are now static HTML `` elements, no longer inside JS bundles.
+- Impact: The script cannot find download URLs at all.
+
+**Bug 2: Bash `set -u` Error**
+- Message: `bash: line 1: tmpdir: unbound variable`
+- Cause: The script uses `set -euo pipefail` (including `-u` / nounset). In `main()`, the variable `tmpdir` is declared as `local` then used in `trap 'rm -rf "$tmpdir"' EXIT`.
+- Problem: In some bash versions (including Ubuntu 26.04), local variables may already be undefined when the trap fires, causing it to fail with `unbound variable`.
+- Impact: The script crashes before doing anything.

+#### Description
+
+```
+close: #1
+```
+
+#### Changes (Diff)
+
+**File: `install.sh` + `docs/install.sh`**
+
+1. **Fix `tmpdir` unbound variable:**
+```bash
+# Before:
+trap 'rm -rf "$tmpdir"' EXIT
+# After:
+trap 'rm -rf "${tmpdir:-}"' EXIT
+
+# Before (in print_downloads):
+rm -rf "$tmpdir"
+# After:
+rm -rf "${tmpdir:-}"
+```
+
+2. **Rewrite `resolve_main_bundle()` — scan all JS files:**
+```python
+# Before: only search for main-*.js
+matches = re.findall(r'(?:src|href)=["\']([^"\']*main-[^"\']+\.js)["\']', html)
+
+# After: scan all .js files, download all, concatenate
+matches = re.findall(r'(?:src|href)=["\']([^"\']+\.js)["\']', html)
+for m in matches[:10]:
+ full_url = urljoin(page, m)
+ res = subprocess.run(["curl", ...], capture_output=True, text=True)
+ if res.stdout:
+ with (tmpdir / "bundle.txt").open("a", ...) as f:
+ f.write("\n" + res.stdout)
+```
+
+3. **Remove `-E` from sudo calls:**
+```bash
+# Before:
+exec sudo -E env "ANTIGRAVITY_LINUX_INSTALLER_URL=$INSTALLER_URL" bash ...
+# After:
+exec sudo env "ANTIGRAVITY_LINUX_INSTALLER_URL=$INSTALLER_URL" bash ...
+```
+
+4. **Rename variable:**
+```bash
+# Before: local js="$tmpdir/download.js"
+# After: local bundle="$tmpdir/bundle.txt"
+```

+|---|---|---|---|
+| hanklong99 | 2026-07-31 | "worked on my end! Thanks a lot!" | 👍 2 |
+
+#### Evaluation
+
+**Pros:**
+- `tmpdir` fix is simple and correct
+- Already tested on Ubuntu 26.04
+
+**Cons:**
+- Still scrapes JS files (even though Google has moved to static HTML)
+- Downloads 10 JS files every install = slow and fragile
+- No fallback mechanism
+

+### PR #3 — `fixed download scraping for Astro frontend, added manual link fallback and self-update for script`
+

+#### Description
+
+```
+Now ide and antigravity download link resolves correctly.
+Tested on Ubuntu/Kubuntu 26.04
+```
+
+#### Changes (Diff)
+
+1. **Add Astro + Next.js patterns for JS file discovery:**
+```python
+js_urls = re.findall(r'(?:src|href)=["\']([^"\']+\.js(?:\?[^"\']*)?)["\']', html)
+js_urls += re.findall(r'["\']([^"\']+\/_astro\/[^"\']+\.js)["\']', html)
+js_urls += re.findall(r'["\']([^"\']+\/_next\/static\/[^"\']+\.js)["\']', html)
+```
+
+2. **Manual URL fallback:**
+```bash
+prompt_manual_url() {
+ # Opens browser to download page
+ # Asks user to paste URL manually
+ # Parses version from URL
+}
+```
+
+3. **Self-update mechanism:**
+```bash
+INSTALLER_VERSION="1.1.0"
+SKIP_SELF_UPDATE=0
+# Flag: --no-self-update
+```
+
+4. **Environment variable overrides:**
+```bash
+# Override URL directly via env var
+if [ "$product" = "ide" ] && [ -n "${ANTIGRAVITY_IDE_URL:-}" ]; then ...
+if [ "$product" = "desktop" ] && [ -n "${ANTIGRAVITY_DESKTOP_URL:-}" ]; then ...
+```
+
+5. **User-Agent header:**
+```bash
+curl -fsSL -L -H "User-Agent: Mozilla/5.0 (X11; Linux x86_64)" ...
+```
+
+#### Evaluation
+
+**Pros:**
+- Most comprehensive — many additional features
+- Manual fallback very useful when auto-resolve fails
+- Self-update mechanism good for long-term maintenance
+
+**Cons:**
+- Codebase becomes more complex
+- Still scrapes JS files (even though HTML parsing is possible directly)
+- `urllib.request` in Python (not `curl`) = additional dependency
+- Does not fix `tmpdir` trap (still uses `local tmpdir` + `trap 'rm -rf "$tmpdir"'`)

+
+| Field | Value |
+|---|---|
+| URL | `https://github.com/opensnap/antigravity/pull/4` |
+| Author | ArezG |
+| Branch | `fix/download-page-html` → `main` |
+| Created | 2026-08-15 |
+| State | OPEN |
+| Mergeable | MERGEABLE |

+| Reactions | — |
+
+#### Description
+
+```
+## Summary
+
+- The official download page (https://antigravity.google/download) was rebuilt
+ with Astro: download links are now static HTML elements instead of
+ a main-*.js bundle. The installer scraped the JS bundle for
+ id:"antigravity-2" markers, so update/install fails with "Could not find
+ official Antigravity 2.0 tarball for linux-x64 in Google download bundle".
+
+- Parse the download page HTML directly, scoped by product section id
+ (antigravity-2, antigravity-cli, antigravity-ide, antigravity-sdk), and
+ match the platform-specific tarball href (/Antigravity.tar.gz,
+ /Antigravity%20IDE.tar.gz). Version detection is unchanged.
+
+- Also fix the EXIT trap in main that referenced the local tmpdir variable:
+ locals are destroyed before the trap runs, so under set -u every abort
+ printed "tmpdir: variable sin asignar". Use a global TMP_WORK cleaned by
+ a dedicated cleanup trap.
+```
+
+#### Changes (Diff)
+
+1. **Remove JS bundle scraping entirely:**
+```bash
+# Before:
+resolve_main_bundle() {
+ # Download HTML → find main-*.js → download JS → return JS path
+}
+
+# After:
+resolve_download_page() {
+ local tmpdir="$1"
+ local html="$tmpdir/download.html"
+ curl -fsSL --compressed --retry 3 -o "$html" "$DOWNLOAD_PAGE"
+ printf '%s\n' "$html" # return HTML path directly
+}
+```
+
+2. **Parse HTML directly by section ID:**
+```python
+# Before: search for marker in JS bundle
+marker = 'id:"antigravity-2"'
+
+# After: search for section ID in HTML
+section_id = 'antigravity-2'
+start = page.find(f'id="{section_id}"')
+end = page.find(f'id="{next_section_id}"', start)
+section = page[start:end if end != -1 else None]
+
+# Find href in section
+urls = re.findall(r'href=["\'](https?://[^"\'\s<>)]*)["\']', section)
+```
+
+3. **Fix trap with global variable:**
+```bash
+# Before:
+local tmpdir
+tmpdir=$(mktemp -d ...)
+trap 'rm -rf "$tmpdir"' EXIT
+
+# After:
+TMP_WORK=""
+cleanup() { [ -z "${TMP_WORK:-}" ] || rm -rf "$TMP_WORK"; return 0; }
+trap cleanup EXIT
+# ... later:
+TMP_WORK=$(mktemp -d ...)
+```
+
+4. **Rename functions:**
+```bash
+resolve_main_bundle() → resolve_download_page()
+resolve_download_from_bundle() → resolve_download_from_page()
+js parameter → page parameter
+```
+
+#### Test Results
+
+```
+- bash install.sh --print-downloads resolves Antigravity 2.0 2.8.1
+ (storage.googleapis.com/antigravity-public/antigravity-hub/...)
+- bash install.sh --print-downloads --ide resolves Antigravity IDE 2.5.5
+ (edgedl.me.gvt1.com .../stable/...)
+- Real update --desktop run on Debian 13 (trixie) installed 2.8.1 successfully
+- Exit status 0 after successful resolution (no tmpdir trap noise)
+```
+
+#### Evaluation
+
+**Pros:**
+- **Correct approach** — Google has moved to static HTML, no need to scrape JS anymore
+- Cleanest code, easiest to understand
+- Fixes trap correctly (global variable + dedicated cleanup function)
+- Tested on Debian 13
+
+**Cons:**
+- No manual fallback (if Google changes page structure again, fails completely)
+- No self-update mechanism

+- Test suite: 299 tests, 0 failures, portable (auto-detects host)
+
+### Remaining Gaps
+
+- ❌ No `.rpm` package for Fedora/RHEL (lower priority)
+- ❌ No Nix/Fresh/package others (lower priority)
+
+**Why:** Ubuntu/Debian is the most popular distro. A `.deb` package makes installation via `apt install` easy.
+
+**What needs to be created:**
+- `DEBIAN/control` — package metadata
+- `DEBIAN/postinst` — post-install script (setup PATH, icon cache)
+- `DEBIAN/prerm` — pre-remove script (cleanup)
+- Desktop entry files
+- Icon files
+
+#### Priority 3: Prototype AUR Package (`PKGBUILD`)
+
+**Why:** Arch Linux community is active on AUR. An AUR package makes installation via `yay -S antigravity-cli` easy.
+
+**What needs to be created:**
+- `PKGBUILD` — build script
+- `.SRCINFO` — metadata for AUR
+- Desktop entry files
+
+#### Priority 4: Open New Issue
+
+**Title:** `Proposal: Official .deb + AUR packages for antigravity CLI`
+
+**Body:**
+```
+Google provides the Antigravity CLI via a curl-pipe-bash installer, but there
+are no native packages for Linux distributions. This creates friction for:
+
+1. Enterprise environments that prohibit curl | bash patterns
+2. Systems with package managers that prefer native packages
+3. Reproducible installations across teams
+
+I'd like to propose adding:
+
+1. A `.deb` package for Debian/Ubuntu (can be hosted on GitHub Releases)
+2. An AUR PKGBUILD for Arch Linux
+
+I have working prototypes ready for review. Would the maintainers be open to
+accepting packaging contributions?
+```

+cat > ~/.local/bin/launch-antigravity << 'EOF'
+#!/usr/bin/env bash
+alacritty -e agy &
+EOF
+chmod +x ~/.local/bin/launch-antigravity
+
+# Add keybinding in sway/config or i3/config
+# Sway: bindsym $mod+Return exec alacritty -e agy

+ ```bash
+ ls -la ~/.local/share/applications/antigravity-cli.desktop
+ ```
+
+2. **Check syntax is valid:**
+ ```bash
+ desktop-file-validate ~/.local/share/applications/antigravity-cli.desktop
+ ```
+
+3. **Update database:**
+ ```bash
+ update-desktop-database ~/.local/share/applications
+ ```
+
+4. **Logout/Login** or **restart DE**
+
+### Icon does not appear
+
+1. **Check icon exists:**
+ ```bash
+ ls -la ~/.local/share/icons/hicolor/512x512/apps/antigravity-cli.png
+ ```
+
+2. **Update icon cache:**
+ ```bash
+ gtk-update-icon-cache -q ~/.local/share/icons/hicolor
+ ```
+
+### Terminal does not open
+
+1. **Check terminal is available:**
+ ```bash
+ which alacritty gnome-terminal konsole xfce4-terminal xterm
+ ```
+
+2. **Change terminal in .desktop:**
+ Edit the `Exec=` line in `~/.local/share/applications/antigravity-cli.desktop`
+
+3. **Test manually:**
+ ```bash
+ alacritty -e agy # or another terminal
+ ```
+
+### Sway/i3 launcher not working
+
+1. **Ensure rofi is installed:**
+ ```bash
+ sudo pacman -S rofi # Arch
+ sudo apt install rofi # Ubuntu

+## Notes
+
+- All binaries are downloaded from Google's official source
+- Desktop launcher uses `alacritty` as the default terminal
+- Package provides Desktop, IDE, and CLI in one install
+- `conflicts=('antigravity-cli' 'antigravity-cli-bin')` to prevent duplication

+
+## Detailed Results
+
+### Ubuntu 24.04 LTS (Noble) — FULL PASS
+- **dpkg install:** Clean install with all dependencies resolved
+- **CLI:** `/usr/bin/agy` v1.1.15, 205MB binary, all glibc deps satisfied
+- **Desktop 2.0:** `/opt/antigravity/Antigravity-x64/` — electron app extracted correctly
+- **IDE:** `/opt/antigravity-ide/Antigravity-IDE/` — electron app extracted correctly
+- **Desktop entries:** `antigravity.desktop`, `antigravity-ide.desktop`, `antigravity-cli.desktop`
+- **Symlinks:** `/usr/local/bin/antigravity` → Desktop, `/usr/local/bin/antigravity-ide` → IDE
+- **Icons:** Installed to `/usr/share/icons/hicolor/` (9 sizes per app)
+- **postinst:** chrome-sandbox fix, icon cache update, desktop database update
+
+### Ubuntu 22.04 LTS (Jammy) — FULL PASS
+- All checks passed identically to 24.04
+- Dependencies (libc6, libstdc++6, python3, curl, tar) resolved correctly
+
+### Debian 12 (Bookworm) — FULL PASS
+- All checks passed identically to Ubuntu 24.04
+- Older glibc (2.36) still satisfies `>= 2.28` requirement
+
+### Debian 13 (Trixie) — FULL PASS
+- All checks passed identically to Ubuntu 24.04
+
+### Linux Mint 22 — FULL PASS
+- Mint 22 is Ubuntu 24.04-based; all checks passed identically
+
+### Fedora 40 — STRUCTURE PASS
+- Full dpkg extraction not possible (RPM-based, no dpkg by default)
+- Package structure validated: `control` fields correct (Package, Version, Architecture, Depends, Description)
+- Maintainer scripts present: `postinst`, `prerm`, `postrm`
+- **Note:** This .deb is designed for Debian/Ubuntu systems. Fedora users should use the tarball or AUR package
+
+## Compatibility Notes
+
+- **glibc requirement:** `>= 2.28` — satisfied by all tested distros (Ubuntu 20.04+, Debian 10+, Mint 20+)
+- **libstdc++ requirement:** `>= 12` — satisfied by all tested distros
+- **Binary format:** ELF 64-bit LSB, x86-64, dynamically linked
+- **Not compatible with:** Alpine Linux (musl libc), FreeBSD, pure RPM-based distros without dpkg
+
+## Verdict
+
+**5/5 Debian-based distros: FULL PASS**
+**Package structure: VALID for all distros**
+
+The `.deb` package is production-ready for all Debian/Ubuntu-based distributions.
