apt-get purge - not working properly [closed]

I've been having really long shutdown times. Today I noticed Ubuntu was stuck on ending a teamviewer process. I don't use it anymore so I decided to remove it.

I tried from the Ubuntu software, but nothing happens. I tried sudo apt-get purge teamviewer but nothing happens.

When I issue dpkg -l | grep team

ic  teamviewer6:i386     6.0.9380   i386         TeamViewer (Remote Control Application)
ii  teamviewer9:i386     9.0.225162 i386         TeamViewer (Remote Control Application)

The teamviewer icon is still available and it still works.

Is there something wrong with APT? I also tried resetting apt with below commands

$ sudo rm -rf /var/lib/apt/lists/*
$ sudo apt-get update**

I'm using UBUNTU 16.04 LTS

Any help appriciated

16.04 is EOL which is off topic but this answer applies to all versions of Ubuntu.

The output of dpkg -l | grep team shows that the package names are teamviewer6 and teamviewer9. To remove these packages, run the following command:

sudo apt purge teamviewer6 teamviewer9

That should work but if it doesn't, run the following:

sudo apt purge teamviewer6:i386 teamviewer9:i386
