Trust my own packages

[Helmut Schneider]

Hi,

I created a few packages using

dpkg-buildpackage

and uploaded them to my ftp server. I ran

apt-ftparchive release ./ > ./Release
gpg --output ./Release.gpg -ba ./Release
apt-ftparchive packages ./ > ./Packages
gpg --output ./Packages.gpg -ba ./Packages

to create the Signatures and imported my own key:

gpg -a --export <myid> | sudo apt-key add -

I then added

deb ftp://192.168.124.35/pub/Ubuntu/ lucid-backports universe

to sources.list

helmut at ubuntu:~/temp/Ubuntu$ find .
.
./Release
./Packages.gpg
./Packages
./pool
./pool/universe
./pool/universe/whois_5.0.20ubuntu1_amd64.deb
./dists
./dists/lucid-backports
./dists/lucid-backports/universe
./dists/lucid-backports/universe/binary-i386
./dists/lucid-backports/universe/binary-i386/Packages.gz
./dists/lucid-backports/universe/binary-i386/Packages
./dists/lucid-backports/universe/binary-amd64
./dists/lucid-backports/universe/binary-amd64/Packages.gz
./dists/lucid-backports/universe/binary-amd64/Packages
./dists/lucid-backports/Packages.gz
./dists/lucid-backports/Release.gpg
./Release.gpg
helmut at ubuntu:~/temp/Ubuntu$

When I now try to update packages with the new ones I receive the
warning:

WARNING: untrusted versions of the following packages will be installed!

How can I trust my own packages?

Thanks, Helmut
