I should probably add this was on CentOS Linux release 7.2.1511 (Core) adding "Patch" keyword, per the suggested fix(es), despite there strictly being no formal patch Just a heads-up - it seems that the fix above isn't applicable to most recent QGIS package (2.14.3-3.el7.x86_64), since the files mentioned don't exist any more. In case it's of any interest, one workaround without having to modify any source code is as follows: # mkdir /usr/share/qgis/python/QtWebKit # touch /usr/share/qgis/python/QtWebKit/__init__.py # echo "from PyQt4.QtWebKit import QWebView" > /usr/share/qgis/python/QtWebKit/QWebView.py Yes it's still of interest. Sadly this fix caused my QGIS to be completly broken. Upon loading it crashes (segmentation fault (core dumped)) I am working on QGIS 2.14.3-3.el7 from the EPEL repository on Scientific Linux release 7.2 (Nitrogen). The processing error has been as noted above. Though QGIS just crashed upon trying to open the Python console. PyQwt doesn't work with Qwt 6 and it would likely take a fair amount to resolve that ( http://lists.osgeo.org/pipermail/qgis-developer/2015-June/038105.html ). Do I understand it correctly that QGIS 2.14 won't be working on Scientific Linux anytime soon then? Will there be a 2.16 release? The plan is to just update to LTRs in EPEL, but there's a COPR for 2.16: https://copr.fedorainfracloud.org/coprs/g/scitech/qgis/ This package has changed maintainer in Fedora. Reassigning to the new maintainer of this component. EPEL 7 entered end-of-life (EOL) status on 2024-06-30.\n\nEPEL 7 is no longer maintained, which means that it\nwill not receive any further security or bug fix updates.\n As a result we are closing this bug. |
Description of problem: Launching QGIS after installation immediately results in the following traceback in the GUI (although the application still launches): -- {Couldn't load plugin 'processing'

for these errors are simple, so I won't bother making a patch, but it's basically a matter of substituting "from QtWebKit.QWebView import QWebView" with "from PyQt4.QtWebKit import QWebView" in the

/usr/share/qgis/python/plugins/processing/ui/ui_DlgHelpEdition.py /usr/share/qgis/python/plugins/processing/ui/ui_DlgAlgorithmBase.py The second error (when launching) is resolved by replacing "from Qsci.qsciscintilla import QsciScintilla" with "from PyQt4.Qsci import QsciScintilla" in the following file: /usr/share/qgis/python/console/ui_console_compile_apis.py Note that the bytecode will need to be recompiled for these fixes to work on a live system. Version-Release number of selected component (if applicable): qgis-2.8.4-1.el7.x86_64 How reproducible: Always Steps to Reproduce: 1. Install QGIS 2. Launch QGIS 3. Launch Python Console in QGIS Actual results: Tracebacks as per description, Python console doesn't work. Expected results: No tracebacks, working Python console. Additional info:
