In previous article i just show you how to install QT 5.5 on lubuntu 15.10, the question is how to remove it? in case you don't need it anymore. In this article i will show you how to uninstall/remove QT 5.5 on lubuntu 15.10. 

Even though i mention about QT 5.5 on lubuntu 15.10, this short tutorial is also can be apply to other version of QT and other version of lubuntu (not just for QT 5.5 and lubuntu 15.10).

Step by step how to uninstall/remove QT 5.5 on lubuntu 15.10

• open terminal/console/command line (press CTRL + ALT + T)
• go to directory where QT 5.5 is installed, the default is ~/Qt5.5.x/ for example mine was ~/Qt.5.5.1/



cd ~/Qt.5.5.1/

Remember that when installing QT 5.5 i told you to install build-essential and openGL library, i strongly suggest that you keep those two, because there is other program that may need those two things.

But if you are insist to remove it anyway, here's the two command that you need to run from the terminal/console/command line:

sudo apt-get purge build-essential

sudo apt-get purge libgl1-mesa-dev
