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?

  1. The manual method links to a specific version of Qt Creator. Installing from a PPA would install whatever version it currently provides, and the Ubuntu SDK PPA offers updates - so it might be have some bug fixes (which may in turn create more bugs).
  2. Installing using apt, which you would if you use a PPA, automatically selects the version for your architecture, so you should get 64-bit by default, unless you specifically call for 32-bit.
  3. Well, a manually installed program updates itself only if the program supports it. So taking care of updates is easier with PPAs than manually installed apps, in general. However I do not know whether Qt Creator offers updates within the program.
  4. gcc-4.9 is yet to arrive in Ubuntu 14.04. The PPA supports whatever version is currently in the release it targets, which would gcc-4.8.x.
  5. The converse - KDE is linked with Qt, because it is built on Qt. Qt Creator runs fine with Ubuntu.
