"Cannot import name QtWebKit" message when installing OpenLayers plugin

redhumus commented 6 years ago

Hi, I'm using a fresh install of Ubuntu Bugie 18.04 on a laptop ASUS X550. I have QGIS 2.18.17 . When I try to install de OpenLayers plugin I receive this error "Cannot import name QtWebKit"

I red different posts, they conclude that the QGIS code doesn't uses anymore the python QtWebKit. Also I red that new versions of QGIS after 2.16 would fix this problem. CAn you help me?

I had the same experience. The error log mentioned a required package. It was, if I recall correctly, python3-pyqt5.qtwebkit

I installed python3-pyqt5.qtwebkit, unistalled the OpenLayers plugin, re-installed.

Success..

Ubuntu, QGIS 3.0.2

Having the same problem, I cannot reproduce that fix/workaround.

The plugin version qgis downloads requires and uses PyQt4, which is not contained in Ubuntu 18.04 anymore. There's just PyQt5. So I don't see how this could work to install python3-pyqt5.qtwebkit, especially since ubuntu's version of qgis uses /usr/bin/python, which is a symlink to python2.7.

So there's two reasons why python3-pyqt5.qtwebkit doesn't seem to help: The 3 and the 5.

@rbracket I have the same issue maybe you are using qgis3

rbracket commented 6 years ago

Yes, I’m using QGIS 3..I forget the version, but my intention is to always have last nights...

I can test again in a few days. No production work going on, just a hobby.

Maybe I found the origin of the problem. Since Qt 5.6 QtWebKitWidget has been replaced by QtWebEngineWidget so since Ubuntu 18.04 uses Qt 5.9 it will never work. We should patch openlayers, porting should not be too difficult http://doc.qt.io/qt-5/qtwebenginewidgets-qtwebkitportingguide.html. Now I don't have time to do a PR I hope will do it soon.

No workaround?

Ubuntu 18.04, QGIS 2.18 here. Is there no solution to this? The same error comes from QuickOSM plugin. I am wondering if the solution here would work for my issue as well.: Couldn't load plugin QuickOSM due to an error when calling its classFactory() method

Just want to say I am affected also on ubuntu 18.04 and qgis 2.18.17.

workaround tip: QuickMapServices : an alternate plugin that's doing the job of putting baselayers and working on QGIS 2.18.17 on my Lubuntu 18.04 64-bit system. Got the tip on https://gis.stackexchange.com/a/131501/44746

The Python bindings of libqtwebkit4 have been removed in Debian Sid and Ubuntu 18.04. QGIS packages from qgis.org now include these Python bindings. So installing python-qgis from qgis.org together with libqtwebkit4 should solve this problem for plugins requiring qtwebkit (LRS, MultiEdit, OpenLayers, qgis2web, QuickOSM, Statist, WFS 2.0 client, WPS client and others).

VincentLeclercq commented 5 years ago

Despite the installation of libqtwebkit4 , the open layer plugin can't be installed on my pc (ubuntu 18.04) Even after reset/restart.

How is it possible?

tvoirand commented 5 years ago

Same here, I installed QGIS 2.18.17 from qgis.org on Ubuntu 18.04, and I installed libqtwebkit4. I still can't import PyQt4.QtWebKit and install the OpenLayers plugin.

TheGrave-zz commented 5 years ago

Ongoing with 2.18.28 on Ubuntu 18.04 and all suggestions above tested.

Workaround for Google Maps (Terrain layer is screwed but the rest is fine):

Same problem here with QGIS 2.18.17 on Ubuntu 18.04.2 LTS and libqtwebkit4 installed. Here's what I get:

Has anyone found a solution or workaround for this Problem? (I cant switch to QGIS 3 because I need a Plugin that's not available for QGIS 3)
