I want to upgrade to a newer version of maven. For that I first want to remove the existing version of maven in the computer as told here. I tried:

sudo apt-get remove maven2

but it says:

$ sudo apt-get remove maven2
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package 'maven2' is not installed, so not removed
0 upgraded, 0 newly installed, 0 to remove and 19 not upgraded.

Then I typed mvn -version just to make sure that maven is not present, but to my surprise I found:

$ mvn -version
The program 'mvn' can be found in the following packages:
* maven
* maven2

Unsure of what to do next, I did locate maven and deleted everything that was present in /usr/share/maven-repo. But after this, if i type mvn -version, it shows the same output that was shown above.

How can I automatically remove maven?

Actually it shows that you already removed it. You can go ahead and use:

sudo apt-get install maven

Try 

sudo apt-get remove maven

instead of maven2.
