Fix sdk command not found after installing SDKMAN.

You need to install following packages before installing sdkman:

sudo apt-get install unzip
sudo apt-get install zip
sudo apt-get install sed

Uninstall skdman if you installed already:

$ tar zcvf ~/sdkman-backup_$(date +%F-%kh%M).tar.gz -C ~/ .sdkman
$ rm -rf ~/.sdkman

Then reinstalled sdkman:

$ curl -s "https://get.sdkman.io" | bash

Next, open a new terminal or enter:

$ source "$HOME/.sdkman/bin/sdkman-init.sh"

Lastly, run the following code snippet to ensure that installation succeeded:

$ sdk version

mine still says
$ sudo apt-get install unzip
-bash: sudo: command not found
can anyone help me?
