This question already has an answer here:
Like, in Windows, in Control Panel, we have Uninstall a Program option, is there anyway I can uninstall a program on Ubuntu? I have installed some programs previously, I do not remember the version and command line i wrote in terminal (because after that, I have used many commands) etc. I searched for a solution on web, and mostly I got an answer, to use Ubuntu software centers. But I do not see many of the softwares I had installed. (For eg. Android Studio, QT. etc) I wish to have a GUI where I can uninstall such programs. Is it possible?
