Silent install Qt run installer on ubuntu server

Question

I wanted to know if there is a way to do a silent install of the Qt run installer on Ubuntu Server?
I mean by-pass the options of the installer and do a default install?

Answer 1

The Qt toolkit is packaged using the Qt Installer Framework (QtIFW). QtIFW installers support a --script option that allows you to programatically control the installation via the Controller Scripting API. Here's qt-installer-noninteractive.qs file to install Qt 5 non-interactively:

// Emacs mode hint: -*- mode: JavaScript -*-

function Controller() {
    installer.autoRejectMessageBoxes();
    installer.installationFinished.connect(function() {
        gui.clickButton(buttons.NextButton);
    })
}

Controller.prototype.WelcomePageCallback = function() {
    // click delay here because the next button is initially disabled for ~1 second
    gui.clickButton(buttons.NextButton, 3000);
}

Controller.prototype.CredentialsPageCallback = function() {
    gui.clickButton(buttons.NextButton);
}

Controller.prototype.IntroductionPageCallback = function() {
    gui.clickButton(buttons.NextButton);
}

Controller.prototype.TargetDirectoryPageCallback = function()
{
    gui.currentPageWidget().TargetDirectoryLineEdit.setText(installer.value("HomeDir") + "/Qt");
    gui.clickButton(buttons.NextButton);
}

Controller.prototype.ComponentSelectionPageCallback = function() {
    var widget = gui.currentPageWidget();

    widget.deselectAll();
    widget.selectComponent("qt.55.gcc_64");
    widget.selectComponent("qt.55.qtquickcontrols");

    // widget.deselectComponent("qt.tools.qtcreator");
    // widget.deselectComponent("qt.55.qt3d");
    // widget.deselectComponent("qt.55.qtcanvas3d");
    // widget.deselectComponent("qt.55.qtlocation");
    // widget.deselectComponent("qt.55.qtquick1");
    // widget.deselectComponent("qt.55.qtscript");
    // widget.deselectComponent("qt.55.qtwebengine");
    // widget.deselectComponent("qt.extras");
    // widget.deselectComponent("qt.tools.doc");
    // widget.deselectComponent("qt.tools.examples");

    gui.clickButton(buttons.NextButton);
}

Controller.prototype.LicenseAgreementPageCallback = function() {
    gui.currentPageWidget().AcceptLicenseRadioButton.setChecked(true);
    gui.clickButton(buttons.NextButton);
}

Controller.prototype.StartMenuDirectoryPageCallback = function() {
    gui.clickButton(buttons.NextButton);
}

Controller.prototype.ReadyForInstallationPageCallback = function()
{
    gui.clickButton(buttons.NextButton);
}

Controller.prototype.FinishedPageCallback = function() {
var checkBoxForm = gui.currentPageWidget().LaunchQtCreatorCheckBoxForm;
if (checkBoxForm && checkBoxForm.launchQtCreatorCheckBox) {
    checkBoxForm.launchQtCreatorCheckBox.checked = false;
}
    gui.clickButton(buttons.FinishButton);
}

This script demonstrates how to select/deselect certain components. Customize for your needs or just remove the lines entirely for a default installation. Likewise, you may want to customize or remove the TargetDirectoryLineEdit line. Run the Qt installer like:

qt-opensource-linux-x64-5.5.1.run --script qt-installer-noninteractive.qs

Add -platform minimal for a headless installation. Future installers based on newer versions of QtIFW should be able to use a --silent option instead (see QTIFW-166).

Add --verbose for more verbose console output (helpful for gleaning component names, wizard page names, etc). This link is also helpful for figuring out component names.

There have few minor different in answering the questions of wizard for a different kind of version of Qt. To make it more simple, I have packed a generic script to extract Qt from an offline/online installer.

The script: qtci/extract-qt-installer at master · benlau/qtci

Example Usage:

extract-qt-installer qt-opensource-linux-x64-android-5.5.1.run ~/Qt

Environment Variables"

VERBOSE [Optional] Set to "true" will enable VERBOSE output
QT_CI_PAGEAGES [Optional] Select the components to be installed instead of using default (eg. QT_CI_PAGEAGES="qt.59.gcc_64")

Moreover, it has few scripts to download and install Qt with different versions.

It's necessary to write in credentials in order to pass through credentials menu. In order to avoid that it's necessary to run docker build command with following network argument:

docker build --network none -t <img_name> <Dockerfile_path>

It was something that was missing in order to succesfully run qt interactive installation in docker.

Answer 4

Take a look at this awesome project: aqtinstall https://github.com/miurahr/aqtinstall/

It can install Qt on Linux, Mac and Windows machines without any interaction.

There's also a Github action that uses this tool: https://github.com/jurplel/install-qt-action

This works for me!

 export DISPLAY=:1
 Xvfb :1 -screen 0 1024x768x16 &
 fluxbox &
 x11vnc -display :1 &

Connect to server using any vnc client

Answer 6

As of installer 3.0.2-online 29-11-2017, you must add a delay in your JS script because the "Next" button in the "Welcome" page is disabled for one second or so.

Controller.prototype.WelcomePageCallback = function() {
    gui.clickButton(buttons.NextButton, 3000);
}

For once, they explain on the 3.2.1-online 29-01-2020 release page how to skip the new form

Controller.prototype.ObligationsPageCallback = function() {
    var page = gui.pageWidgetByObjectName("ObligationsPage");
    page.obligationsAgreement.setChecked(true);
    page.completeChanged();
    gui.clickButton(buttons.NextButton);
}

Some may wonder how to create the mysterious qtaccount.ini file (required since 3.2.1-2-online). Qt only tells us that it should be placed in ~/.local/share/Qt/. I was unable to find any other information. The installer creates this file itself when you enter your credentials for the first time. So simply do a manual installation and quit after the accound form. The generated file looks like

[General]
email=my.email@domain.ca
pass=mypass

[QtAccount]
email=my.email@domain.ca
jwt=a long hash
u=a small hash
