- Fixed script crashes from `whiptail` Cancel/Esc under `set -e`. Added `_menu()`, `_checklist()` and `_inputbox()` wrappers with `|| true` to prevent premature exits.
- Resolved startup failures by using defaults instead of relying on unset variables with `set -u`.
- Hardened sudoers management — `_validate_sudoers()` writes to temp file, validates with `visudo -cf`, only copies if successful.
- Replaced `eval` in `_run_cmd` with safer `bash -c` execution.
Swap Management Module (`modules/swap.sh`)
- New standalone module with 9 internal functions and `manage_swap()` entry point.
- Btrfs CoW detection — applies `chattr +C` before swapfile creation to prevent mkswap rejection on Btrfs.
- Dynamic swappiness configuration — reads current system value instead of hardcoding 60, pre-fills inputbox with existing setting.
- Uses `/run/lock/debianito-swap.lock` for early init compatibility (added as option 9 in main menu).
Repository & Branch Migration (`modules/repos/migrate.sh`)
- Handles branch migration from stable (11/12) to Testing or SID with 5-screen UX flow.
- Persistent backup system — creates timestamped tar.gz backups of `/etc/apt/sources.list*`, auto-restores on apt update failure.
- SID guardrails — installs `apt-listbugs` and `apt-listchanges` before upgrade to warn about critical bugs in unstable packages.
- Dynamic menu options based on Debian version (SID shows only 1-2-3 Exit, non-SID includes backports + branch migration).
- New `_components_enabled()` helper detects current contrib/non-free state.
Gaming Module Overhaul
- Unified gaming checklist — merged i386 toggle into single prompt with lazy evaluation instead of separate pre-check.
- Lazy 32-bit architecture enablement — only enables i386 when needed (steam/lutris/i386 selected) and installs graphics drivers if `need_32bit=true`.
- New `_install_nvidia_32bit()` helper with proper driver detection, version pinning, and legacy/tesla variant handling.
Heroic & OpenRGB Downloads
- Heroic — fetches latest release from GitHub API using `jq` to extract amd64.deb URL, validates with `dpkg-deb --info`.
- OpenRGB — downloads from Codeberg Gitea API with SHA256 verification when available, fallback to `dpkg-deb` validation.
- Dynamic codename detection — now detects Bookworm vs Trixie at runtime instead of hardcoded static values for .deb download URLs.
|Other Improvements
- Renumbered main menu: 8=ZRAM, 9=Swap Management, 10=Extras, 11=Boot Rescue, 12=Exit.
- Improved `detect_storage()` — excludes loop/CD-ROM devices via `lsblk -e 7,11`, explicitly skips zram, detects USB/SD via `/sys/block/$name/removable`.
- Standardized SCROLL_HINT across all files with centralized readonly variable.
- Created standalone modules/bluetooth.sh for `_install_bluetooth_stack()` with desktop-aware frontend selection (bluedevil/KDE, blueman/XFCE/other). Extracted from `firmware.sh`, reducing it from 438 to 369 lines.
- Added `detect_desktop_environment()` and `detect_audio_server()` functions in `utils.sh` with new globals `DESKTOP_ENV=""` and `AUDIO_SERVER=""`.
- New `found_active_wifi` flag detects Qualcomm Atheros AR9485 PCI chips without loaded firmware, displaying `(no driver — install firmware)` instead of silently disappearing. Auto-installs `firmware-atheros + firmware-linux-nonfree` after Firmware & Wireless Setup.
- New `is_nvidia_blackwell()` detects GPUs in ranges `0x2900–0x29BF` and `0x2B80–0x31FF`. Added `_enable_cuda_repo()` helper for extrepo-based CUDA installation with APT pinning. DKMS verification blocks added to all `_install_nvidia_*` functions.
- Standardized repository enablement across 7 modules using `_enable_*_repo()` helpers:
- `internet.sh`: Firefox/Floorp/LibreWolf, Pale Moon, Tailscale, Mullvad VPN/Browser, ProtonVPN
- `jellyfin.sh`, `programming.sh` (VSCodium), `java.sh` (Temurin)
- New `extras/office/office.sh`: OnlyOffice + LibreOffice with language detection
- The main script was reduced from 233 to 137 lines. Created new `modules/sysinfo.sh` (97 lines) for `_show_sysinfo()`. Source chain: `utils.sh → sysinfo.sh → sudo_config.sh → repos → firmware.sh → bluetooth.sh → gpu.sh → kernel.sh → gaming.sh → extras.sh → zram.sh → java.sh`.
- Renamed menu to `"Firmware, Wireless & Bluetooth"`. Translated NTP dialog (English), basic programs install message, and NVIDIA 32-bit legacy messages.
- Replaced the restrictive head -n1 hardware parsing with a dynamic while read loop. The script now fully detects and registers multiple coexisting GPUs (Intel+Nvidia / AMD+Nvidia).
- Rewrote install_gpu_drivers() in modules/gpu.sh from a mutually exclusive case block to independent, sequential if conditions. Laptops now install both integrated firmware (Intel/AMD with non-free VA-API acceleration) and dedicated graphics stacks (Nvidia driver + 32-bit libs for Steam) seamlessly in a single pass.
- Improved Nvidia Kepler architecture guards under Debian 13 (Trixie). The script now safely skips missing legacy Nvidia packages without aborting or crashing the remaining Intel/AMD configurations.
- Added nvme-cli utility installation across all Debian versions. For Bookworm and Trixie, it features dynamic hardware validation via lsblk transport filtering and interactive, real-time SMART log viewing with an execution screen-pause.
- Created a brand new standalone module (modules/extras/dev/jellyfin.sh) to cleanly inject Jellyfin Media Server across Debian 11, 12, and 13 using its official setup script, protected by strict SHA256 checksum validations and guaranteed error-cleanup.
- Added OpenRGB to the Gaming menu for Debian 12 and 13. Implemented secure curl downloads with an emulated Chrome User-Agent to bypass Codeberg bot blocks, complete with automatic i2c-dev module configuration, user groups provisioning, and udev permission rules execution.
- Standardized menu headers across 15 separate files using a centralized readonly SCROLL_HINT=" [↑↓]" variable, replacing messy hardcoded strings with clean, uniform Whiptail instructions.
- update README.md
- Refactored `is_backports_enabled()` to dynamically detect backports using `DEBIAN_CODENAME` instead of hardcoded strings, improving script portability.
- Added support for standalone classic backports files (`/etc/apt/sources.list.d/debian-backports.list`) and deb822 format (`*.sources`) to ensure consistent detection across different repository configurations.
- Resolved Mesa and Kernel backports detection bugs, ensuring correct dialogue prompts and preventing false error messages during installation.
- Implemented smart rounding for zram memory allocation to the nearest Gigabyte for optimized performance.
- Enhanced Whiptail manual input validation for zram to block empty, non-numeric, or zero values.
- Introduced a dedicated `software_centers.sh` module for the modular and clean installation of GNOME Software and Plasma Discover.
- Added smart desktop environment detection (GTK/QT) to automatically suggest and install the optimal software center.
- Implemented a two-phase installation flow for software centers (Base Store -> Optional Flatpak support) with static consistency warnings based on the detected desktop environment.
- update README.md
- Created dedicated `extras/java.sh` module for modular Temurin/Adoptium repository handling and isolated GPG key management.
- Implemented selective JRE/JDK installation paths: Gaming (Minecraft) vs Development environments with version control selectors.
- Enhanced user group membership logic (`_ensure_sudo_group`) to auto-configure administrative privileges on fresh installs.
- Introduced maintenance-friendly passwordless sudo for `apt`, `systemctl`, and shutdown commands via `/etc/sudoers.d/`.
- Added home directory ownership repair utility to fix root-owned files in user directories after improper `sudo` usage.
- Enabled visual password feedback (`pwfeedback`) toggle for enhanced terminal usability during authentication prompts.
- Refactored Debian 13/Trixie repository sourcing logic to ensure idempotency and prevent backports/duplicate sources conflicts.
- Updated Bullseye legacy modules (extras.sh, repos.sh) to exclude deprecated packages (`hx`, `vscodium`) and enforce Firefox ESR defaults.
- Cleaned repository configurations by removing obsolete `bullseye-updates` source entries to prevent dependency conflicts.
- Implemented NVTOP conditional detection logic ensuring display only on active Nvidia drivers or supported architectures (Trixie/Bookworm).
- Corrected `/modules/bullseye/extras.sh` menu mappings (Programming, Dev Tools) and verified package lists excluding incompatible tools (`hx`, `vscodium`).
- Integrated ClamAV security module with daemon state management and background scan execution flows in all Security menus.
