Uninstalling VIVADO from Ubuntu 18.0

I have installed vivado on my Ubuntu 18.0 but i am having difficulties in trying to uninstall it.

I tried the two following tutorials but their methods did not work for me.

Uninstalling program

Firstly i do no not have the directory that is mentioned at the second tutorial `

/opt/folder you have installed Xilinx/.xinstall/bin/lin` 

There is no /bin file ate the up-mentioned directory. What i have are the following files:

/.xinstall/DocNav
/.xinstall/Vivado_2018.2
/.xinstall/xic

So any help on how to uninstall it?

go to [install dir]/.xinstall/Vivado_2018.2/bin and run terminal from there and put the ff command:

"sudo ./xsetup -Uninstall"

First go to your Xilinx instalation folder, then look for xsetup binaries:

<Xilinx_installation_folder>$ find . -name xsetup

Outputs would correspond to all installed Xilinx application and their xsetup binaries.

For the Xilinx application you want to Uninstall, go to the folder where xsetup is located for that application and run:

<Xilinx_program_you_want_to_delete_folder>$ sudo ./xsetup -Uninstall
