# Zupt + Zupt GUI — Install Guide for Linux
|
|
|
|
If you're seeing the error:
|
|
|
|
```
|
|
zupt-gui depende de python3-pyqt6 | python3-pyside6; porém:
|
|
Pacote python3-pyqt6 não está instalado.
|
|
zupt-gui depende de zupt (>= 2.2.3); porém:
|
|
Versão de zupt no sistema é 2.1.7-1.
|
|
```
|
|
|
|
This is correct behavior. The `zupt-gui` deb requires:
|
|
- Python 3 with **PyQt6** or **PySide6** (the GUI toolkit)
|
|
- The **zupt CLI 2.2.3** 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. Done.
|
|
|
|
## 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 zupt CLI to 2.2.3
|
|
sudo dpkg -i zupt_2.2.3_amd64.deb
|
|
|
|
# 3. Install the GUI
|
|
sudo dpkg -i zupt-gui_1.1.1_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 zupt-2.2.3-1.x86_64.rpm zupt-gui-1.1.1-1.noarch.rpm
|
|
```
|
|
|
|
(Or build the RPM from the SRPM tarball with `rpmbuild -bb SPECS/zupt.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 zupt from the source tarball
|
|
```
|
|
|
|
### Anything else (or no apt/dnf/pacman handy)
|
|
|
|
Use the AppImage — no install needed:
|
|
|
|
```bash
|
|
tar xzf Zupt-GUI-1.1.1-x86_64.AppDir.tar.gz
|
|
cd zupt-gui.AppDir
|
|
./AppRun
|
|
```
|
|
|
|
The AppImage still needs Python 3 + Qt6 binding on the host (those are
|
|
universally available on every Linux distribution since 2022). 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 Zupt 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 every major Linux distribution
|
|
since 2022, 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 zupt 2.2.3?
|
|
|
|
The GUI calls `zupt --pq-sdk` and `zupt keygen --sdk` for state-of-the-art
|
|
post-quantum encryption (HKDF-SHA3 hybrid combiner, key commitment, HPKE
|
|
binding, Argon2id). These flags didn't exist in 2.1.7 — they were added
|
|
in 2.2.0.
|
|
|
|
If you have an older zupt installed, the GUI's compress/extract will fail
|
|
with "unknown option --pq-sdk".
|
|
|
|
## After installing — verify
|
|
|
|
```bash
|
|
zupt version # should show: 2.2.3
|
|
zupt-gui # should launch the GUI window
|
|
```
|
|
|
|
## If the GUI window still doesn't appear
|
|
|
|
```bash
|
|
# Run from terminal to see error messages
|
|
zupt-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 zupt-gui still won't work, open an issue
|
|
at https://git.securityops.co/cristiancmoises/zupt/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 `zupt version`
|
|
5. Output of `zupt-gui` (the error message it printed to terminal)
|

## Building from source
|
|
|
|
If you want to build Zupt from the source tarball instead of installing
|
|
the pre-built `.deb` / `.rpm` packages, you'll need:
|
|
|
|
### Build dependencies
|
|
|
|
| Component | Why needed |
|
|
|---|---|
|
|
| `gcc` ≥ 7 or `clang` ≥ 10 | C11 compiler |
|
|
| `make` | build driver |
|
|
| `libargon2-dev` | Argon2id KDF |
|
|
| `libssl-dev` | OpenSSL libcrypto (AES, SHA-256) |
|
|
| **`libzuptsdk-dev` 2.0.0+** | Zupt's cryptographic SDK |
|
|
|
|
The `libzuptsdk-dev` package is a separate sister project — it contains
|
|
the post-quantum hybrid cryptography that Zupt uses on its `--pq-sdk`
|
|
path. Both libraries are by the same author (Cristian Cezar Moisés) but
|
|
are distributed as separate source/binary packages so each can evolve
|
|
on its own release cadence.
|
|
|
|
### Install build dependencies (Debian/Ubuntu/Mint)
|
|
|
|
```bash
|
|
sudo apt install build-essential libargon2-dev libssl-dev
|
|
|
|
# Then install libzuptsdk from its package:
|
|
sudo apt install ./libzuptsdk2_2.0.0_amd64.deb \
|
|
./libzuptsdk-dev_2.0.0_amd64.deb
|
|
```
|
|
|
|
### Install build dependencies (Fedora/RHEL/openSUSE)
|
|
|
|
```bash
|
|
sudo dnf install gcc make libargon2-devel openssl-devel
|
|
# libzuptsdk from its SRPM:
|
|
tar -xzf libzuptsdk-2.0.0.srpm.tar.gz
|
|
rpmbuild -bb SPECS/libzuptsdk.spec
|
|
sudo rpm -i ~/rpmbuild/RPMS/x86_64/libzuptsdk-2.0.0-*.rpm
|
|
```
|
|
|
|
### Build Zupt itself
|
|
|
|
```bash
|
|
tar -xzf zupt-2.2.3-source.tar.gz
|
|
cd zupt-2.2.3
|
|
|
|
make # build the `./zupt` binary
|
|
sudo make install # install to /usr/local/bin (override with PREFIX=/usr)
|
|
|
|
./zupt version # verify
|
|
```
|
|
|
|
The `make` step takes 10-30 seconds. The build emits the binary as
|
|
`./zupt`. The default install prefix is `/usr/local`; override with
|
|
`PREFIX=/usr` for system-wide install.
|
|
|
|
### Run the test suite
|
|
|
|
```bash
|
|
make test
|
|
```
|
|
|
|
61 tests pass: roundtrip, audit, multi-file, cross-block, dedup property,
|
|
path-traversal, argument-order, block-swap regression. Each suite reports
|
|
its own pass/fail count.
|
|
|
|
### Cross-compilation
|
|
|
|
Zupt 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).
|
|
|
|
### Static linking against libzuptsdk
|
|
|
|
If you want a fully self-contained `zupt` binary (no `libzuptsdk.so.2`
|
|
runtime dependency), you can link against the static library:
|
|
|
|
```bash
|
|
make LDLIBS='-l:libzuptsdk.a -lcrypto -largon2'
|
|
```
|
|
|
|
This produces a binary that doesn't need `libzuptsdk2` installed at
|
|
runtime — useful for containers, embedded systems, or distribution to
|
|
machines without package management.
