registrating clients doesn't work when installing the package

Binary package hint: landscape-client

If apt is run with a debconf priority of medium landscape account information is asked during the package installation. However landscape-config fails:

Setting up landscape-client (1.0.18-0ubuntu1) ...
 * Running update-motd failed.
 * Reloading system message bus config... [ OK ]
Traceback (most recent call last):

    import gobject
ImportError: No module named gobject

The reason is that the package python-gobject uses python-support which uses dpkg triggers to install python modules. Since dpkg triggers are run after all postinst scripts, the gobject module is not available when landscape-client.postinst calls landscape-config.

At a first glance it seems most of the work done by landscape-config could be done in the postinst script. The only issue is sending the registration request to the landscape server.

NB: in order to use debconf at medium priority when installing packages, modify the apt configuration:

mathiaz@t-landscape:~$ cat /etc/apt/apt.conf.d/70debconf
// Pre-configure all packages with debconf before they are installed.
// If you don't like it, comment it out.
DPkg::Pre-Install-Pkgs {"/usr/sbin/dpkg-preconfigure --apt --priority=medium || true";};
