i get below takehome test

Download the source code of a Debian package.===> i selected a example package "hello"
Add an executable bash script called “testing.sh”

    When executing the testing.sh will echo “this is a test from yuan tao ” on the standard error (STDERR).

Please echo the string “this is a test from yuan tao” during the Debian package installation time.
Push all of your change to a public git repository (e.g. launchpad git, Github or GitLab)
dput the source change to your ppa on the launchpad.

To make it a triage-package and upload to ppa, i need to have a bug-ID to fill in the debian/changelog,
otherwise, there will be lintian warnings "W: hello: new-package-should-close-itp-bug"

The dev environment i am using is an ubuntu20.04 LTS running in virtual machine, the hypervisor is windows10 hyper-V
