Dirk,

Is expected that doc jobs will be occasionally failing due to unmet
dependencies or inability to get the dpkg lock?

I just looked at the groovy doc job for pocketsphinx, and there are a
number of failed builds (
http://jenkins.willowgarage.com:8080/view/Gdoc/job/doc-groovy-pocketsphinx/).
Most end with:

Executing command 'apt-get install ros-groovy-ros ros-groovy-genmsg --yes'
Reading package lists...
Building dependency tree...
Reading state information...
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 ros-groovy-ros:i386 : Depends: ros-groovy-catkin:i386 but it is not
going to be installed
                       Depends: ros-groovy-rosbash:i386 but it is not
going to be installed
                       Depends: ros-groovy-rosbuild:i386 but it is not
going to be installed
                       Depends: ros-groovy-rosclean:i386 but it is not
going to be installed
                       Depends: ros-groovy-roscreate:i386 but it is
not going to be installed
                       Depends: ros-groovy-roslang:i386 but it is not
going to be installed
                       Depends: ros-groovy-roslib:i386 but it is not
going to be installed
                       Depends: ros-groovy-rosmake:i386 but it is not
going to be installed
                       Depends: ros-groovy-rosunit:i386 but it is not
going to be installed

    raise BuildException(msg)
common.BuildException


Is this something I'm doing wrong?

Also, the most recent job failed with:

E: Could not get lock /var/lib/dpkg/lock - open (11: Resource
temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is
another process using it?


Thanks for any feedback,
