Recently I installed Facebook Messenger in my Ubuntu 14.04 and then I noticed that it is no longer supported in Ubuntu. So I tried to uninstall it. When I checked Software Center I can't find an entry for Facebook Messenger there.
The following are the commands I used to install Facebook Messenger:
sudo add-apt-repository ppa:nilarimogard/webupd8 sudo apt-get update sudo apt-get install fbmessenger
So how can I uninstall Facebook Messenger ?
