DAK documentation

Please note that dak's documentation is not up-to-date. (dak has switched to python3 and dependencies are not documented)

fasttrack-team maintains a "federated" branch of dak to allow binaries without source in the fasttrack dak instance (but for which source is present in upstream/official debian repos). See for why.

The federated branch is meant to be kept up-to-date with the upstream dak master.

Upgrading dak

git fetch origin
git checkout -b newbranch
git rebase origin/master
git diff newbranch oldbranch # inspect changes
# apt install new-dependencies
dak update-db

SSH upload

Add this to ~/ for ssh upload (for unreliable connections)

login   = root
# login = another_username
fqdn    =
method  = sftp
incoming        = /srv/dak/queue/unchecked/
allow_dcut      = 1
# Please, upload your package to the proper archive
allowed_distributions   = (?!UNRELEASED|.*-security)

Accept packages

dak process-upload -d /srv/dak/queue/unchecked # SSH uploads
dak process-upload -d /srv/ftp/pub/UploadQueue/ # anonymous ftp uploads
dak process-new
dak process-policy new
dak generate-packages-sources2
dak generate-release

Remove Packages

We should remove packages from buster-backports suite when they are accepted into official archive.

dak rm -s buster-backports -C <email> <package name>

Mention 'Accepted into official buster I backports' as reason.

dak dominate
dak clean-suites
dak generate-packages-sources2
dak generate-release

Modifying Suite Configurations

To instruct package manager to assign priorities as defined here for a suite, do

dak admin s-cfg set <suite-name> notautomatic=True butautomaticupgrades=True

The changes will be reflected in the release file when release for the suite are generated on the next try. With the above option package manager will assign a priority of 100 for the packages from the release.

Add new architecture

Example for adding armhf for buster-fasttrack

$ dak admin architecture add armhf "Arm Hard Float Port"
$ dak admin suite-architecture add buster-fasttrack armhf
$ dak init-dirs

Add new suite

Example for adding bookworm-fasttrack

$ dak admin suite add-all-arches bookworm-fasttrack 12.0 origin=Debian label=BookwormFasttrack codename=bookworm-fasttrack
$ dak init-dirs

When accepting golang packages in NEW

You need to change the section of some golang packages to devel when accepting them from NEW.

dak@fasttrack:~$ dak process-new && dak process-policy new

Add new OpenPGP keys for upload access

Download the keys on your local machine,

First find the OpenPGP keyid using wkd

$ gpg --locate-keys email@domain.tld # if they have setup wkd - see

or from

$ gpg --search email@domain.tld # if the key is also available in, take keyid and download from

Or from

And download keys from

$ gpg --keyserver --recv-key 0xkeyid
$ gpg --export --armor 0xF34F09744E9F5DD9 >name.key.asc
$ scp name.key.asc

On fasttrack server,

# ~/keys# gpg --no-default-keyring --keyring /srv/dak/keyrings/upload-keyring.gpg --import name.key.asc
# su - dak
$ dak import-keyring -U '%s' /srv/dak/keyrings/upload-keyring.gpg

Server Configuration


Allow all outgoing traffic

Block all incoming traffic

Open tcp ports 21 open for ftp.

Open few ports in the range 100xx to 10xxx for passive mode.

Open 80,443 port for http and https


Disable authentication via password for openssh-server

Add PasswordAuthentication no to /etc/ssh/sshd_config


Return 404 for files that shouldn't be publicly served


Set the following options in /etc/vsftpd.conf

anon_upload_enable=YES # Enables anonymous upload

write_enable=YES # Enables write to be permitted

pasv_enable=YES # Enables passive mode for ftp 



local_enable=NO # Disables login using local account in the server

The passive mode requires a small range of tcp ports (you can chose 10 as a range value) to be enabled. The pasv_max_port value should be greater than pasv_min_port value for the range to be proper.
