Every time when I start my QGIS I see the following message:

GRASS init error: Problem in GRASS initialization, GRASS provider and plugin will not work : Module built against version $Revision: 64733 $ but trying to use version $Revision: 67364 $. You need to rebuild GRASS GIS or untangle multiple installations.

This problem has appeared on Friday. And I am not able to find out what caused this issue. I work in Ubuntu Trusty Tahr 14.04 LTS. QGIS version is 2.12.3-Lyon.

Could someone help me to solve the problem with QGIS and GRASS?

  • I can confirm that this error also occurs on Ubuntu 15.10 Feb 17, 2016 at 22:32
  • I had to uninstall GRASS using apt: sudo apt-get remove qgis-plugin-grass Feb 18, 2016 at 10:15
  • Have tried the nightly versions of QGIS and Grass71 but still displays the same error. No such issues with the same installations from 'Osgeo4w' on Windows. Feb 20, 2016 at 15:39
  • This problem is also occurring in LTR version 2.18.27.
