Hi,

running debsign failed
yes, you have to sign them.
By default the key is searched with a match on the debian/changelog last entry.
You can override it by exporting
export DEBEMAIL='youremail'
export DEBFULLNAME='name surname'
export DEBSIGN_KEYID='key fingerprint'
export DEB_SIGN_KEYID='key fingerprint'
on your bashrc file.
this way you can sign with no issues and your key changes file with a signature
from somebody else
(e.g. your sponsor will have to do it)
cheers,
G.
