Image build failing for QT v 5.14.1

After QT’s open-source repository was down for a few days, QT components v 5.14.1 (referred to by Splash’s Dockerfile) are no longer available in QT’s repository. Re-building the Docker image fails.

Reverting to QT version 5.12.10 allows image build to succeed, but the container started from the resulting image crashes with the following log.

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/app/splash/server.py", line 12, in <module>
    from splash.qtutils import init_qt_app
  File "/app/splash/qtutils.py", line 15, in <module>
    from PyQt5.QtWebKit import QWebSettings
ImportError: libQt5QmlModels.so.5: cannot open shared object file: No such file or directory

https://www.docker.com/blog/compiling-qt-with-docker-multi-stage-and-multi-platform/ may be an interesting read

Oh, there’s https://download.qt.io/archive/qt/5.14/

So I guess for the time being a simple URL change may do the trick.

Upgrading Qt later will not be trivial, though. It’s starting to look like we will need to have the image build it from source. Maybe we need to find or create a Docker image that provides a Qt build, so that this Dockerfile does not take forever to build.
