Cannot build udeb with debhelper 13.6ubuntu1

[Andre Wagner]

Hi,
I'm trying to rebuild a traditional server installer, therefore I've to build Debian-Installer udeb Packages. But this does not work with debhelper 13.6ubuntu1 on the actual ubuntu 22.04 prerelease. I found the root cause: It's ubuntu specific patch on debhelper described in debian changelog as "Imply '<!noudeb>' profile if not set on package type udeb". I reverted that patch and now the build of udebs works again.

Greetings,
André
