# VaptVupt + VaptVupt GUI — Install Guide for Linux
|
|
|
|
If you're seeing the error:
|
|
|
|
```
|
|
vaptvupt-gui depende de python3-pyqt6 | python3-pyside6; porém:
|
|
Pacote python3-pyqt6 não está instalado.
|
|
vaptvupt-gui depende de vaptvupt (>= 4.2.1); porém:
|
|
Versão de vaptvupt no sistema é 2.1.7-1.
|
|
```
|
|
|
|
This is correct behavior. The `vaptvupt-gui` deb requires:
|
|
- Python 3 with **PyQt6** or **PySide6** (the GUI toolkit)
|
|
- The **vaptvupt CLI 4.2.1** or newer
|
|
|
|
## The fastest fix — one command (Linux Mint, Ubuntu, Debian)
|
|
|
|
Put all the downloaded files in the same folder, then:
|
|
|
|
```bash
|
|
sudo bash install-zupt-gui.sh
|
|
```
|
|
|
|
This script auto-detects your distribution and installs everything in
|
|
the right order.
|
|
|
|
## Manual fix — three commands (if you prefer)
|
|
|
|
### Linux Mint / Ubuntu / Debian / Pop!_OS
|
|
|
|
```bash
|
|
# 1. Install the Qt6 Python binding
|
|
sudo apt update
|
|
sudo apt install -y python3-pyqt6
|
|
|
|
# 2. Upgrade vaptvupt CLI to 4.2.1
|
|
sudo dpkg -i vaptvupt_4.2.1_amd64.deb
|
|
|
|
# 3. Install the GUI
|
|
sudo dpkg -i vaptvupt-gui_1.3.0_all.deb
|
|
```
|
|
|
|
If step 3 still complains about deps, run:
|
|
|
|
```bash
|
|
sudo apt --fix-broken install
|
|
```
|
|
|
|
### Fedora / RHEL / Rocky / AlmaLinux
|
|
|
|
```bash
|
|
sudo dnf install -y python3-pyqt6
|
|
sudo dnf install -y vaptvupt-4.2.1-1.x86_64.rpm vaptvupt-gui-1.3.0-1.noarch.rpm
|
|
```
|
|
|
|
(Or build the RPM from the SRPM tarball with `rpmbuild -bb SPECS/vaptvupt.spec`)
|
|
|
|
### openSUSE Leap / Tumbleweed
|
|
|
|
```bash
|
|
sudo zypper install python3-pyqt6
|
|
# Build the RPM from the source tarball — see the SRPM .tar.gz
|
|
```
|
|
|
|
### Arch Linux / Manjaro / EndeavourOS
|
|
|
|
```bash
|
|
sudo pacman -S python-pyqt6
|
|
# Build vaptvupt from the source tarball
|
|
```
|
|
|
|
### Anything else (or no apt/dnf/pacman handy)
|
|
|
|
Use the AppImage — no install needed:
|
|
|
|
```bash
|
|
tar xzf VaptVupt-GUI-1.3.0-x86_64.AppDir.tar.gz
|
|
cd vaptvupt-gui.AppDir
|
|
./AppRun
|
|
```
|
|
|
|
The AppImage still needs Python 3 + Qt6 binding on the host. For a
|
|
fully standalone executable with no Python dependency, use a future
|
|
PyInstaller-built version (not in this release).
|
|
|
|
## Why does the GUI need Qt6?
|
|
|
|
The VaptVupt GUI is written in Python, using either PyQt6 or PySide6 (it
|
|
auto-detects whichever is installed). These are bindings to the Qt 6
|
|
graphical toolkit — they're how the GUI draws windows, buttons, and
|
|
dialogs.
|
|
|
|
PyQt6 is in the default repositories of major Linux distributions, so
|
|
installing it is one apt/dnf/zypper/pacman command away. We don't bundle
|
|
Qt6 inside the deb because:
|
|
|
|
- It's already on most modern systems
|
|
- Bundling would make the deb 80 MB+ instead of 35 KB
|
|
- Distribution-managed Qt gets security updates automatically
|
|
|
|
## Why does the GUI need vaptvupt 4.2.1?
|
|
|
|
The GUI calls `vaptvupt --pq` and `vaptvupt keygen` for native
|
|
post-quantum encryption (ML-KEM-768 + X25519, in-tree implementation).
|
|
Older CLI versions lack these flags, so the GUI's compress/extract will
|
|
fail against them.
|
|
|
|
## After installing — verify
|
|
|
|
```bash
|
|
vaptvupt version # should show: 4.2.1
|
|
vaptvupt-gui # should launch the GUI window
|
|
```
|
|
|
|
## If the GUI window still doesn't appear
|
|
|
|
```bash
|
|
# Run from terminal to see error messages
|
|
vaptvupt-gui
|
|
|
|
# If you see "ImportError: No module named 'PyQt6'":
|
|
# The GUI fell back through both PyQt6 and PySide6 imports.
|
|
# Re-check: python3 -c 'import PyQt6.QtWidgets'
|
|
|
|
# If you see "DISPLAY not set":
|
|
# You're on SSH without X forwarding. Use ssh -X or run locally.
|
|
|
|
# If you see "qt.qpa.plugin: Could not load the Qt platform plugin":
|
|
# Missing Qt platform plugin. On Mint/Ubuntu:
|
|
# sudo apt install qt6-qpa-plugins
|
|
```
|
|
|
|
## Reporting issues
|
|
|
|
If you've tried the above and vaptvupt-gui still won't work, open an issue
|
|
at https://git.securityops.co/cristiancmoises/vaptvupt/issues with:
|
|
|
|
1. Output of `lsb_release -a` (or `cat /etc/os-release`)
|
|
2. Output of `python3 --version`
|
|
3. Output of `python3 -c 'import PyQt6; print(PyQt6.__version__)' 2>&1`
|
|
4. Output of `vaptvupt version`
|
|
5. Output of `vaptvupt-gui` (the error message it printed to terminal)
|

## Building from source
|
|
|
|
If you want to build VaptVupt from the source tarball instead of installing
|
|
the pre-built `.deb` / `.rpm` packages, you'll need only a C compiler and
|
|
make. The default build has NO external crypto dependency and installs no
|
|
shared library.
|
|
|
|
### Build dependencies (default build)
|
|
|
|
| Component | Why needed |
|
|
|---|---|
|
|
| `gcc` ≥ 7 or `clang` ≥ 10 | C11 compiler |
|
|
| `make` | build driver |
|
|
| libm, pthread | math and threading (part of the standard C library/toolchain) |
|
|
|
|
The default build uses PBKDF2-SHA256 (600k iterations) for password KDF
|
|
and the in-tree native `--pq` mode (ML-KEM-768 + X25519) for post-quantum
|
|
encryption. No `libzuptsdk`, no OpenSSL, no libargon2 is required.
|
|
|
|
### Install build dependencies (Debian/Ubuntu/Mint)
|
|
|
|
```bash
|
|
sudo apt install build-essential
|
|
```
|
|
|
|
### Install build dependencies (Fedora/RHEL/openSUSE)
|
|
|
|
```bash
|
|
sudo dnf install gcc make # Fedora/RHEL
|
|
sudo zypper install gcc make # openSUSE
|
|
```
|
|
|
|
### Build VaptVupt itself
|
|
|
|
```bash
|
|
tar -xzf vaptvupt-4.2.1-source.tar.gz
|
|
cd vaptvupt-4.2.1
|
|
|
|
make # build the `./vaptvupt` binary
|
|
sudo make install # install to /usr/local/bin (override with PREFIX=/usr)
|
|
|
|
./vaptvupt version # verify
|
|
```
|
|
|
|
The `make` step takes 10-30 seconds. The build emits the binary as
|
|
`./vaptvupt`. The default install prefix is `/usr/local`; override with
|
|
`PREFIX=/usr` for system-wide install.
|
|
|
|
### Run the test suite
|
|
|
|
```bash
|
|
make test
|
|
```
|
|
|
|
Covers roundtrip, multi-file, cross-block, dedup property, path-traversal,
|
|
argument-order, and block-swap regression. Each suite reports its own
|
|
pass/fail count.
|
|
|
|
### Cross-compilation
|
|
|
|
VaptVupt builds on x86_64, aarch64, armhf, ppc64le, s390x, and riscv64. To
|
|
cross-compile:
|
|
|
|
```bash
|
|
make CC=aarch64-linux-gnu-gcc # for AArch64
|
|
make CC=arm-linux-gnueabihf-gcc # for ARMv7 (Raspberry Pi 32-bit)
|
|
```
|
|
|
|
The Makefile auto-detects target architecture via `$(CC) -dumpmachine`
|
|
and selects the appropriate SIMD flags (NEON on AArch64, SSE4/AVX2 on
|
|
x86_64).
|
|
|
|
### Optional: WITH_SDK=1 build
|
|
|
|
The SDK-backed modes — `--pq-sdk`, `--pq-box` (sealed-box), and the
|
|
Argon2id KDF — are optional. They are not in the default build and require
|
|
building against the separately distributed `libzuptsdk` / `libpqvaptvupt`
|
|
libraries:
|
|
|
|
```bash
|
|
make WITH_SDK=1
|
|
```
|
|
|
|
This build additionally needs the SDK development package and its runtime
|
|
dependencies (OpenSSL libcrypto, libargon2), which ship with the SDK
|
|
distribution. Without `WITH_SDK=1`, the `--pq-sdk` and `--pq-box` flags are
|
|
unavailable; use the native `--pq` mode instead.
