Description

Steps to reproduce:

1. install QGIS 3.0
2. Open / Open Advanced Setting / OK / Close application
3. uninstall QGIS 3.0
4. install QGIS 3.2.2
5. Open application
6. Open Setting
5. click OK
6. A dialog complains "GRASS7 Folder" is invalid

wrong value for parameter GRASS7 folder....

7. Open Setting / Goto advance config
8. Processing / Configuration / GRASS7 Folder remains to QGIS3.0's grass folder

I'm not sure if this also happens with Linux.
I'm not sure this should be filed under category "GUI" or "Windows Package".

  • Category changed from GUI to Processing/GRASS

#2 Updated by Alexander Bruy over 5 years ago

  • Status changed from Open to Feedback

This is expected and correct behaviour. QGIS does not wipe its settings when reinstalled or updated. Note that all other setting also does not reset, so why Processing settings should change?

I just think it took me a bit long time to find out the location of settings, perhaps my bad anyway.
So I can come up with two resolution.

1. Installer should always reset the grass folder to the default location of new GRASS in the package.
(or perhaps a checked checkbox at setup for those who want to opt out.)

2. The advanced configuration warning should give details of exact setting path to look for like:
"Advanced Configuration / Processing / Configuration / GRASS7 Folder"

#4 Updated by sand thorn over 5 years ago

In version 3.4
Settings / Advanced / Processing / Configuration / GRASS7 Folder
seems not affected and unused.

However, one might still find "GRASS7 folder" error when clicking "OK" in Advanced setting after upgrade.
The coresponding setting now moves to
Settings / Processing / Providers / GRASS / GRASS7 folder

Manually change those settings to current installation path will suppress the warning.

try a new/clean profile.

Last night I had a similar experience with installing QGIS 3.4 using OSGeo4W. I got a "can't find grass.bat" error when trying to run grass algorithms in qgis. Eventually I figured out that OSGeo had installed Grass 7.6 and I used it to install Grass 7.4 and it started working again. But not after I learned that the path to grass folder is no longer in Options/Processing/Providers/Grass and I did not find it in options/advanced/processing/(no configuration folder) or in any of the advanced setting that I could find.
