* GRASS tools are not available in the processing toolbox. Of course I
did the following
In order to fix such issue, you could either:
- modify the line 132 of the file grass_utils.py (in
\apps\qgis-ltr\python\plugins\grassprovider\)
from
if "GRASS GIS " in line:
to
if "GRASS " in line:
I did these changes yesterday night based on an AI search and the
following AI explanation: "During startup, QGIS executes a command line
script to verify that GRASS is responsive. It scans the resulting text
output line-by-line looking for the phrase "GRASS GIS " to confirm a
valid installation. However, modern GRASS releases changed their
terminal output format and no longer include the word "GIS "—they just
output "GRASS " followed by the version number. This discrepancy causes
the unpatched QGIS script to throw a critical error . By deleting the
word "GIS " (keeping the trailing space after GRASS), the script
successfully detects the modern GRASS startup string, passes the
verification check, and allows your profile .ini paths to load the tools
into your Processing Toolbox ."
The AI also recommended to do the following: Search for the qgis3.ini
file in the folder C:\Users\User
Name\AppData\Roaming\QGIS\QGIS3\profiles\<Profile_Name>\QGIS\, open
qgis3.ini in a text editor, search for the code block starting with
[Processing], adding the following two lines to force QGIS to look for
GRASS at the specific path where GRASS is actually placed by QGIS:
Configuration\GRASS8_FOLDER=C:/OSGeo4W/apps/grass/grass84
Configuration\block_grass=false
It seems that modifying grass_utils.py is sufficient, but this might be
another problem/solution for other users.
- or downgrade the installed OSGeo4W grass package from 8.5.0-1 to
8.4.2-3 and the installed qgis-ltr* packages from 3.44.1-2 to 3.44.11-1.
- or install QGIS LTR 3.44.11 using the OSGeo4W "offline" standalone
.msi installer, instead of the OSGeo4W "online" installer
* SAGA plugin Processing SAGA NextGen Provider is not available.
The "Processing SAGA NextGen Provider" plugin is no longer available
on the official QGIS plugins' repository.
You can find a copy of the last version that was once available on the
QGIS plugins' repository at
https://github.com/agiudiceandrea/qgis-processing-saga-nextgen/releases/tag/1.1.0
You could download the zip file
https://github.com/agiudiceandrea/qgis-processing-saga-nextgen/releases/download/1.1.0/processing_saga_nextgen-1.1.0.zip
and install it in QGIS using the Plugin Manager.
Regards.
Andrea
