[Qgis-user] QGIS 3.22 - GRASS Init-Error

[Martin Bittens]

Hello Alister,

in the meantime I did an update on a second computer from QGIS 3.20.3 to
QGIS 3.22.0, and from QGIS 3.16.11 to 3.16.13 using the OSGEO4W
installer. The result is:

QGIS 3.22.0 displays the GRASS init error, the GRASS 7 plugin cannot be
used, the GRASS processing algorithms are working.

QGIS 3.16.13 is working without any problems. Both, the GRASS 7 plugin
and the GRASS processing algorithms can be used.


As far as I understood the GRASS 7 plugin in QGIS 3.22 'want to see' a
GRASS version which is not installed whereas the GRASS 7 plugin which
came with QGIS 3.16.13 is satisfied with the installed GRASS version.
But I do not have any idea how telling the GRASS 7 plugin of QGIS 3.22
that it should take what is installed.


Regards


Martin
