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?
