How to Properly Install JetBrains Toolbox on Linux (Kubuntu/Ubuntu)

JetBrains Toolbox for Linux comes as a tar archive, not a .deb package. Here's the proper way to install it: 1. Download and extract the archive 2. Move files to `/opt/jetbrains-toolbox` (standard location for third-party apps) 3. Create symbolic link: `sudo ln -s /opt/jetbrains-toolbox/jetbrains-toolbox /usr/local/bin/` 4. Install icon: `sudo cp toolbox-tray-color.png /usr/share/pixmaps/` 5. Add to menu: copy .desktop file to `~/.local/share/applications/` 6. Update menu cache: `update-desktop-database ~/.local/share/applications/` **Result:** Toolbox appears in "Development" menu, autostarts with system, and lives in system tray. All JetBrains IDEs can be installed/updated from one place. **Why bother:** Stay with PhpStorm/PyCharm/WebStorm while using latest AI features (Junie, Codex, Agent Skills) — no need to switch to VS Code.
