I upgraded my Ubuntu 14.04 development system to 16.04 in August with the first point release. I have to say the upgrade process when really smooth. There where small issues with PHP and Python. The only painful issue I had was with Cassandra and CqlSh. The python version which is shipped with Ubuntu 16.04 is 2.7.12 and the version CqlSh is targeted is 2.7.11. When I tried to connect to CqlSh I got the following error:
