The latter steps of this guide assumes you have a webserver set up to serve the repo directory you will be creating in this guide.
GPG key for signing
Run the following command as the user you intend to sign stuff with:
Select option 4 to create a RSA key. Default keysize of 2048 is alright. Enter your name and email when prompted.
Public GPG key
Replace the email below with your own:
gpg --armor --export firstname.lastname@example.org > pubkey.gpg
Packages you build from now on should be automatically signed with the key you have generated if the email match the one in the changelog file.
To resign existing packages run:
dpkg-sig --sign builder package.deb
Builder is a Debian convention, no need to change that. Only replace package.deb with the file name of your package.
Setting up the repository
Create a new directory for the repo, containing another directory called conf:
mkdir -p repo/conf
Then create a file called "distributions" in the conf directory:
Origin: apt.example.com Label: apt repository Codename: wheezy Architectures: amd64 Components: main Description: Description of your fabulous repo SignWith: yes Pull: wheezy
Adding packages to the repository
For this we use a great tool called "reprepro":
apt-get install reprepro
Add packages with the below command, note that you need to be in your repo directory:
reprepro --ask-passphrase -Vb . includedeb wheezy /path/to/your/package.deb
Make the public key available
I suggest you put the public key we created earlier, "pubkey.gpg" in the root of the repo or somewhere else where it can be downloaded like this:
wget -q -O - http://example.com/repo/repokey.gpg | sudo apt-key add -
