The best advice is not to update GRASS unless a new point release 
version of QGIS has been compiled.

ubuntugis stable has GRASS 7.2.2 for Trusty , see 
https://launchpad.net/~ubuntugis/+archive/ubuntu/ppa/

If you have already installed a newer version, you have to remove and 
purge the downloaded packages, then run sudo apt-cache policy GRASS to 
see what is available for you.

Or take QGIS 2.14 and GRASS 7.4 from ubuntugis unstable by disabling 
qgis.org.
