I'm used to an environment where I run the qt designer/qt assistant simply typing designer/assitant in the terminal. I am talking about qt 4. I've been installing packages such as qtcreator and qt4-default, but I get this:
~$ assistant
assistant: could not exec '/usr/lib/x86_64-linux-gnu/qt4/bin/assistant': No such file or directory
~$ designer
designer: could not exec '/usr/lib/x86_64-linux-gnu/qt4/bin/designer': No such file or directory
sudo updatedb; locate bin/assistant
