I once installed Reader from the Adobe website. It was full of bugs and didn't come with text in the menu so I decided to uninstall it and install a different version. I tried:
sudo apt-get autoremove acroread
sudo apt-get remove acroread
sudo apt-get purge acroread
In the end the program still stayed on my computer and managed to launch. Then I installed nearly the same version of Reader from the Software Center. The one from the Software Center worked perfectly but I still have the buggy version. How do I remove it? I have tried searching for it in the Software Center but didn't find it there. Thankfully PDF documents open with the new version but when I search the program in the launcher, I see 2 exact icons of Reader.
