I have found PPA and manual method to install Qt Creator 3.1.2 on Ubuntu 14.04 LTS.
Which one is more reliable (has less bugs once installed)? The manual method offers 64 bit installation. What if I install using the PPA method? Will the 64 bit version be installed into 64 bit Ubuntu? May I expect some problems if not? Which one updates itself with Ubuntu? Is GCC 4.9.1 supported?
I reckon that Qt Creator is somehow linked with KDE. Shall I expect some problems when using Qt Creator with Ubuntu intead of Kubuntu?
