I removed ganache, ganache-cli from terminal.
npm ls ganache shows nothing
But still I can see ganache gui. I want to remove the ganache gui fully. Please help.
Finally I figured out. Ganache GUI is basically executable which run directly. Simply delete that exe and download new. Done.
Incase you are unable to find exe location - In Ubuntu desktop shortcut are saved at location /home/<user>/.local/share/applications. Check the respective file and you'll get actual location of exe.
