Problem

I had a following error(debian-rules-is-dh_make-template) from lintian.

How should I fix to pass the error?

The message showed me that I didn't modify debian/rules, but I already modified (I added override_dh_auto_clean:), so I guess that my debian/rules is insufficient but I can't figure out why my debian/rules is insufficient...

$ lintian hello_2.10-0ubuntu1.dsc --info

Background

I'm trying to do the tutorial(https://packaging.ubuntu.com/html/packaging-new-software.html#starting-a-package).

By using default debian/rules, I had a error like this(https://bugs.launchpad.net/ubuntu-packaging-guide/+bug/1248353/).

Therefore, I added override_dh_auto_clean: in my debian/rules for workaround(https://bugs.launchpad.net/ubuntu-packaging-guide/+bug/1248353/comments/10).

How about delete commentary in debian/rules?

#!/usr/bin/make -f
%:
        dh $@

override_dh_auto_clean:
        echo clean
