I think I read on this forum that you could not upgrade from 2.8 to 3.0 because you have to reinstall 3.0. (I couldn't find it searching.) Why would something like what is this article http://www.omgubuntu.co.uk/2016/04/how-t...-16-04-lts for upgrading from Ubuntu 14.04 LTS to Ubuntu 16.04 LTS work? ???
It would save having to install/uninstall software, themes, icons, etc.
