Packaging Kopano and related packages

Kopano is the free open source variant of the Kopano Collaboration Platform from Zarafa packaged for Debian. Kopano is the renamed Zarafa Collaboration Platform (ZCP) by Zarafa B.V. as a consequence started by a complete license change to AGPL started in 2015. Some parts are completely rewritten (like the archiver functions) and got integrated in the Kopano release from scratch.

Resources

Current State

kopanocore version 8.1.0-3 is in unstable. kopano-webapp isn't finally packaged and is not available by the Debian repositories, the packaging process is mostly finished. Other kopano-* packages aren't packaged yet or prepared. z-push has got a prepared packaging (see further down) but this needs probably some attention.

libvmime

kopano-server, kopano-utils, kopano-dagent, ...

ToDo

  • Check place of the database while install (local or remote) -> Debconf

  • Fix Lintian errors and warnings
  • Review and forward patches against libical (for libvmime we don't need this any longer, see above) on upstream.

  • Test full functionality
    • We'd need some Outlook users here, too...
  • test and fix init scripts
    • systemd compatibility
    • error out when database is missing
    • often hangs on stop
  • systemd unit files (partially done)
  • MTA integration
  • check package descriptions
  • logrotate (upstream available in installer/linux/kopano.logrotate, put in zarafa-common, split it per package)
  • check pre-/postinstall scripts: they do no error handling, don't include debhelper snippets
  • z-push upstream update
  • do not run as UID 0 (problematic for kopano-search, otherwise it is configurable in the config files and done in the Debian packages)
  • kopano-common: kill it with fire, no useful parts, still true?
  • Adding mechanism to not conflict with packages from upstream
  • Autopkgtests
  • check for unneeded linked libraries and forward upstream

Further possible improvements:

  • Tweak default SSL settings in gateway.cfg and server.cfg
  • Add some security features to systemd service files (PrivateTmp=True, etc.)

Done

  • (./) import upstream version 8.1.0

  • (./) switch to debhelper 9

  • (./) Use dbconfig-common/Debconf to generate the initial configuration

    • database name
    • database user
    • database login
  • kopano-client:
    • Rename zarafa-client to libzarafa-client0 since it contains no client programs ??
    • make libkcclient a proper version-ed shared lib (it's currently a private one) ??
  • (./) Adding some basic autopkgtests

kopano-webapp

ToDo

  • Lintian is complaining about
    • tinymce (TinyMCE currently overridden as Debian version is to old)

    • Fonts in the package (related to TinyMCE)
  • Adding mechanism to not conflict with packages from upstream

Done

z-push/d-push

The d-push packages, the debranded Debian version of z-push, are outdated so far and removed in testing. The license for the z-push source has been also changed to AGPL3 by Zarafa/Kopano. By this the re-brand isn't needed any longer. Kopano stated about a interest that z-push will be updated to recent versions, but it wasn't found the way into the Stretch release.

ToDo

  • Update the package repository to a recent version
  • Update the Debian packaging stuff to recent versions and workflow
  • Transmigrate the existing d-push packages into z-push variants
  • Use package names from upstream, but decrease to a minimum if possible

  • Create autopkgtests tests where possible
  • Ensure a smooth update on the user side

Roel van Meer is currently on working on the z-push packages https://github.com/roelvanmeer/z-push-packaging


The origin of this topics is provided by GuidoGünther in https://honk.sigxcpu.org/piki/agx/publications/2011-06-debian-groupware-zs.pdf.

There was also a talk given on the Zarafa Tour 2015 in Hannover (in german)Talk-Hannover-ZarafaTour2015.pdf. On the Kopano Conference in 2016 Guido was giving also a talk about the current state of Kopano in Debian.


Using KVM for testing

You probably wont use your current system to test the kopano packages and that's a good idea so far. KVM is a good alternative for testing because it's supporting snapshot mechanism for easy using and resetting of installations.

Installing needed KVM components

Installation is easy as it's simply a one liner.

$ sudo apt-get install qemu-kvm bridge-utils virt-manager virtinst

Further preparations

After this ensure you are a member of the group 'libvirt'

$ sudo usermod -aG libvirt [YOUR_USERNAME]

The virtual network adapter inside the libvirt environment is disabled per default so before to continue start it.

$ virsh -c qemu:///system net-autostart default
$ virsh -c qemu:///system net-start default

The next calls maybe not really needed, but on the other hand it's no problem if the storage pools already up, so just to throw possible issues away.

$ virsh -c qemu:///system pool-start default
$ virsh -c qemu:///system pool-start boot-scratch

Installation of a virtual image

After the finishing of the preparation from above you can install a first image. The installation can be done as known done fully automated by a preseed file, Guido has prepared file preseed.cfg. Download the file for example to the 'Downloads' folder within your home directory.

$ wget -P $HOME/Downloads http://honk.sigxcpu.org/projects/libvirt/preseed/preseed.cfg

Next you can set up a install, for example based on the unstable release amd64 and named unstable-amd64-kopano.

$ RELEASE=unstable
$ NAME=kopano
$ DIST=amd64
$ virt-install --connect=qemu:///system \
               --cpu host \
               --os-variant linux \
               --location="http://ftp.us.debian.org/debian/dists/$RELEASE/main/installer-$DIST" \
               --initrd-inject=$HOME/Downloads/preseed.cfg \
               --extra-args="auto" \
               --name $RELEASE-$DIST-$NAME --ram=512 \
               --disk=pool=default,size=10,format=qcow2,bus=virtio

This will install a image named 'unstable-amd64-kopano.qcow2' with a size of 10GB under /var/lib/libvirt/images/. After the install the image will boot automatically.

pkg-giraffe package repository

Using packages from Alioth

Packages are available at https://pkg-giraffe.alioth.debian.org/packages/ . These can be included into a file /etc/apt/sources.list.d/pkg-giraffe.list, for unstable on AMD64 for example, via

deb http://pkg-giraffe.alioth.debian.org/packages unstable/amd64/
deb http://pkg-giraffe.alioth.debian.org/packages unstable/all/

Releases are signed with GPG key 0xAE3AAB3E2F45C0A0 which can be added to a system as trusted key using apt-key by the following command:

wget -O - https://pkg-giraffe.alioth.debian.org/0xAE3AAB3E2F45C0A0.asc | sudo apt-key add -

The fingerprint of the key is:

pub   rsa2048/0xAE3AAB3E2F45C0A0 2016-10-27 [SC] [expires: 2021-10-26]
      Key fingerprint = 87A1 0F8A 9174 E939 F4AB  C2A7 AE3A AB3E 2F45 C0A0
uid                   [ultimate] Debian pkg-giraffe archive key <pkg-giraffe-maintainers@lists.alioth.debian.org>

To delete the key in the local key store run:

sudo apt-key del 0xAE3AAB3E2F45C0A0

Uploading packages to Alioth

In order to upload packages to the repo on Alioth you need to be member of the pkg-giraffe group and have Alioth ssh access set up. Uploads can be done via dput using the following configuration:

[pkg-giraffe]
fqdn = alioth.debian.org
incoming = /home/groups/pkg-giraffe/htdocs/packages/mini-dinstall/incoming
method = scp
allow_unsigned_uploads = 0
post_upload_command = ssh alioth.debian.org "mini-dinstall -b -c /home/groups/pkg-giraffe/.mini-dinstall.conf"

As signed uploads are needed, your key needs to be in the keyring file "pkg-giraffe-keyring.gpg" on Alioth.
