QGIS » QGIS Application

I managed to locate the file on my system:

"/lib64/python3.6/site-packages/PyQt5/uic/widget-plugins/qgis_customwidgets.py"

I can confirm that renaming/deleting the file fixes the issue with the graphical modeler.

It seems to me that this file should be removed/disabled until these issues can be fixed. As it stands, the graphical modeler is broken on Linux (or at least on two Linux platforms).

Fresh install of QGIS 3.0.

I am experiencing the same issue referred to in these issues: #17488 (see screenshot), #18065 and #18194

The fix is supposed to be deleting "qgis_customwidgets.py" from the folder "usr/lib/python3/dist-packages/PyQt5/uic/widget-plugins" but evidently the file structure is different on the RPM version, as this file does not exist.

Note that I recently switched from Linux Mint 18.3, where I experienced an identical issue. Deleting the above file did not completely solve the issue in that case.

I had no issues with the graphical modeler in QGIS 2.18.

It's only the case if you had previously installed a dev version of 2.99 -- an installation of the final 3.0 release doesn't have this issue.

This doesn't seem to be correct. This bug occurred with a completely new install of QGIS -- version 3.0.0-Girona -- that did not have any version previously installed. I had completely formatted my computer and changed distros earlier that day -- February 24.

This is the build (from February 23):
