I only ever installed the offline version and the last I installed on Debian
Wheezy was qt 5.2 but it went smoothly.
I don't remember I had to be root to install it but I may be wrong on this.
The installer creates a Qt directory in your $HOME directory and copies the
libraries, binaries, examples, documentation and QtCreator into it (for
instance, the current version would be in $HOME/Qt/Qt5.4.1).
You can install several versions of the Qt librairies and binaries. They all
use distinct subdirectories in $HOME/Qt. As a consequence, you must not forget
to manually unintall older versions when you don't need them any more.
QtCreator is configured to detect existing Qt librairies on the system and in
your home directory. You just select the library version you want to use to
build your project.
If you build your project against the Qt librairies installed in your home
directory, you can still release your application you include a copy of every
required so file within the application directory. Don't forget to distribute
your application with the platform directory (I don't remember where it is).
