I just installed QT Creator 2.4.1 (Based on QT 4.8.0 64bit) from Ubuntu Software Center and noticed that it was not the latest version. How do I upgrade it from terminal? My Ubuntu is 12.0.4LTS.




The regular ubuntu repositories don't contain the latest version of QT or QT Creator, you will first have to add an ppa via the command line:

sudo add-apt-repository ppa:ubuntu-sdk-team/ppa

Now you can update:

sudo apt-get update
sudo apt-get upgrade

If this doesn't work, try removing QT Creator first and then reinstalling with:

sudo apt-get install qtcreator
