Bug#789868: pbuilder: pdebuild fails with sudo error

[Vincent Lefevre]

Package: pbuilder
Version: 0.215+nmu3
Severity: normal

When following the steps in

  https://www.debian.org/doc/manuals/maint-guide/build.en.html#pbuilder

I get the following error when running "pdebuild":

sudo: sorry, you are not allowed to preserve the environment

Note that I use sudo's default config.

With "/bin/bash -x pdebuild", I can see a line starting with:

  sudo -E pbuilder --build --buildresult /var/cache/pbuilder/result/ [...]

But it seems that for security reasons, the -E option no longer works.
So, this would no longer be the right method.
