Error when running install-scala-env

Hi,

Many thanks for your detailed Git tutorial series on Youtube. I was trying to follow along the Part 11 video which required installing Scala environment and used the script in install-scala-dev. However, I ran into an error, with the output shown below. May I know how to resolve this please? Also, is there an uninstall script to uninstall the Scala environment that is installed using the script?

chmod +x scala-env && ./scala-env

Should we update ~/.profile? [Y/n] Y
Some shell configuration files were updated. It is recommended to close this terminal once the setup command is done, and open a new one for the changes to be taken into account.
