Ah...
Now I see 2.7 ????
That is very old, please upgrade to the one available via
https://qgis.org/en/site/forusers/alldownloads.html#fedora
Much thanks for your replies.
I've done this, but this has led to another issue. Either it's a bug or
I'm not executing something correctly (clicking checkboxes etc.
If I go Database -> DB Manager
Establish a connection to my postgresql/postgis database
F2 to open the SQL editing window, type:
SELECT * FROM "shapefiles"."us_states" WHERE state = 'Texas'
Hit Execute, Load As layer
Nothing appears in either the Layers pane or the main window.
However, if I go
Layer -> Add Layer -> Add PostGIS Layers
and then select a table built upon a shapefile
the map loads.
I can then edit the SQL for that layer by right-clicking on the layer in
the layer pane, Update sql, and my modifications are reflected in the
layer.
How do I get DB Manager to add a layer?
Much thanks,
Max Pyziur

Hi Max,
The error means that the python-cpp bridge is not working because wrong
paths to (python) libs.
Are you maybe in a Python Virtual Environment at that moment, which in
that case screws up your python path?
Or else: did you miss some QGIS-Python package (if installed via package
manager)?
Regards,
Richard Duivenvoorde

Greetings,
My use of QGis Desktop is occassional; when I do use it, I construct
layers using PostGIS & PostgreSQL.
The key component that facilitates this in QGis is a Python plugin
called DB Manager.
When I started Qgis today, there was an error message that appeared
something like this:
Couldn't load PyQGIS. Python support will be disabled.
Traceback (most recent call last):
File "", line 1, in
File "/usr/lib64/python2.7/site-packages/qgis/gui/__init__.py", line
27, in
from qgis._gui import *
RuntimeError: the PyQt4.QtCore module failed to register with the sip
module
Python version:
2.7.15 (default, Oct 15 2018, 15:26:09)
[GCC 8.2.1 20180801 (Red Hat 8.2.1-2)]
QGIS version:
2.18.20 'Las Palmas', exported
After clicking away the error away, the existing layers that I had built
using PostGIS/PostgreSQL were still available in my key critical project.
However, when I went to look for DB Manager, it wasn't available.
After some searching, I upgraded to QGIS 3.6 from a non-Fedora
repository (the guidance is here:
https://stackoverflow.com/questions/53716778/the-pyqt4-qtcore-module-failed-to-register-with-the-sip-module)
and now I have access to the DB Manager functionality.
Is the Fedora/QGis community aware of this issue?
Thanks!
Max Pyziur
