unbuntu下卸载QT
方法一：
you can remove it like this, those developers should add this somewhere ! like next to the download text
linuxmint ~ # cd /opt
linuxmint opt # ls
qtsdk-2010.04
linuxmint opt # sudo ./qtsdk-2010.04/bin/uninstall
linuxmint opt #


方法二：
You can use the updater i think. Just unselect everything that you installed before and let it run
But I can’t find the QT SDK in updater.
In Qt Creator

Menu help > start updater …
