My installation of tortoisehg on Ubuntu 20.04 and newer

install.sh

#!/bin/bash

TARGET_DIR=~/Downloads/repos/third-parties
TORTOISEHG_VERSION=${5:-stable}

prepare() {
    sudo apt-get -y update
    
    sudo apt-get -y install \
    curl \
    gcc \
    make \
    mercurial \
    python-is-python3 \
    python3 \
    python3-dev \
    python3-distutils \
    python3-docutils \
    python3-dulwich \
    python3-iniparse \
    python3-pip \
    libxcb-xinerama0
    
    pip3 install PyQt5 QScintilla mercurial

    mkdir -p ${TARGET_DIR}
}

install_tortoisehg() {
    echo 'Starting install_tortoisehg'

    cd ${TARGET_DIR}
    rm -rf thg || true
    rm /usr/local/bin/thg || true
    
    hg clone -u ${TORTOISEHG_VERSION} https://foss.heptapod.net/mercurial/tortoisehg/thg
    
    sudo mkdir /usr/local/bin/ || true
    sudo ln -fs ${TARGET_DIR}/thg/thg /usr/local/bin/thg
}

main() {
    set -xe

    prepare
    install_tortoisehg
}

main

I had to also run sudo apt-get install libxcb-xinerama0 because if not I got a Qt error:

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb.

Use

sudo apt-get install '^libxcb.*-dev' libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev libxkbcommon-dev libxkbcommon-x11-dev

Hello, what OS are you running? Ubuntu 22.04 has tortoisehg in apt so you can just install it hassle-free. I haven't used this script in years because it's no longer needed.

I Use Ubuntu 22.04, Yes I try snap, apt, and it's the same error

sudo apt install tortoisehg
