Unknown module(s) in QT: webenginewidgets

Cannot obtain the lock for file "/home/j/.cache/qt-unified-linux-online/cache.lock": Resource temporarily unavailable

Is Qt Online Installer still running? If so close it and try again.
If it does not help delete that file manually.

I've removed all components with Maintenance tool, then reinstalled
Qt and Web engine with online installer

Trying to compile sample project:

QT += widgets webenginewidgets
CONFIG += c++17
SOURCES += main.cpp

#include <QApplication>
#include <QWebEngineView>
#include <QUrl>

int main(int argc, char *argv[]) {
    QApplication app(argc, argv);

    QWebEngineView view;
    view.resize(1200, 800);
    view.load(QUrl(QStringLiteral("https://www.qt.io")));
    view.show();

    return app.exec();
}

getting error:
:-1: error: Unknown module(s) in QT: webchannel positioning

Kindly advise!

webchannel positioning

Same: did you install these two modules?

@JacobNovitsky If you are using the Qt version from the online installer, you have to add these dependencies from the online installer as well...

Or just use the Qt version from your distribution. However you cannot mix and match.

Should I install above libraries with version 6.9.2? (as per my Qt version)

@JacobNovitsky You should install these libraries for the Qt version you're using.
You wrote:

Doesn't that mean that you now need to install these modules using Qt Maintenance Tool from that Qt installation?

All modules installed, version of module is the same as Qt -> 6.9.2

QT += core gui widgets webenginewidgets   # <-- webenginewidgets is required

CONFIG += c++17

    view.show();

    return app.exec();
}

@JacobNovitsky when you say all modules installed:

from the same source ?
are you using the Qt version with all the modules installed to build your application ?
