I'm that kind of user who likes to have different browsers, media players, etc. Today I just wanted to try out Opera and Google Chrome, but I don't want to use them anymore so I thought that I remove them. The problem is I can't find them in Ubuntu Software Center or when I use 'remove opera' in terminal it doesn't work. Can you tell me how to remove them properly?
Are you sure that you have installed these two pieces of software successfully?
dpkg -s opera-stable google-chrome-stable
If you see
dpkg-query: package 'nlll' is not installed and no information is available that means you didn't install that.
Also, if you install that, you will see lots of files.
