Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

Let's go. I have a local deb repository. It works fine. But every time when I update my software there is a warning "You are about to install software that can't be authenticated". I decided to sign my local repository. My repo structure:

/var/www/deb/repo/deb/dists/stable/main/soft_1.0.0-0_amd64.deb
/var/www/deb/repo/deb/dists/stable/main/binary-amd64/Packages.gz

I created a gpg key and imported it on my repo server and on my ubuntu. Also I created a Release file in each binary-amd64 and binary-i386. After that I calculated checksums and signed my repository.

apt-ftparchive release dists/stable/main/binary-amd64 >> dists/stable/main/binary-amd64/Release
gpg -abs -o dists/stable/main/binary-amd64/Release.gpg dists/stable/main/binary-amd64/Release

After signing I got new files in my repository

/var/www/deb/repo/deb/dists/stable/main/binary-amd64/Release
/var/www/deb/repo/deb/dists/stable/main/binary-amd64/Release.gpg

Release file:

Archive: stable
Suite: stable
Component: main
Origin: mySoft
Label: soft-deb-repo
Architecture amd64

And Release.gpg:

-----BEGIN PGP SIGNATURE-----
Version: GnuPG v1.4.10 (GNU/Linux)

-----END PGP SIGNATURE-----

But problem won't disappear - when I check update by Package Manager it says that my software can't be authenticated. Aptitude says WARNING: untrusted version of the following packages will be installed. What do I do wrong?

I had to create an InRelease File to solve the authentication problem. I solved this by reading apt-secure in the manual pages. I also had to create a Packages file (unzipped) as well. Here are the two commands:

gpg --clearsign -o InRelease Release
gpg -abs -o Release.gpg Release

My directory structure and files looks like this to help you better understand what I am doing.

shift@shift-VirtualBox:~/shiftRepo$ ls -R
.:
dists  shiftCPEKey

./dists:
stable

./dists/stable:
main

./dists/stable/main:
binary

./dists/stable/main/binary:
CPEDataCollector_1.0+SNAPSHOT.deb  CPEQueueConsumer_1.0+SNAPSHOT.deb  Packages     Release
CPEQueueBroker_1.0+SNAPSHOT.deb    InRelease                          Packages.gz  Release.gpg
