Delete chromedriver from Ubuntu

I want to update the version of chromedriver that I installed following this instruction https://christopher.su/2015/selenium-chromedriver-ubuntu/

To do this, I want to delete the current version. I tried to do this by finding the desired folders with the

whereis chromedriver

command. And deleting the files from there using rm. But

chromedriver -v

still gives the value of the old version. What is another way to completely remove the current chromedriver?Also i tried just update following this topic How to update Chromedriver on Ubuntu?But chromedriver -v still return old version
