Hi, apologies if this is the wrong topic to put this in (if so, please move/advise), but I have a package that is failing to build on the buildfarm and I can’t immediately see why.

The package is ` ros-kinetic-mongodb-store` for 15.04 (jessie).

An instance of the job is here: [http://build.ros.org/job/Kbin\_djv8\_dJv8\_\_mongodb\_store\_\_debian\_jessie\_arm64\_\_binary/5/console](http://build.ros.org/job/Kbin_djv8_dJv8 __mongodb_store__ debian_jessie_arm64__binary/5/console)

It appears to be failing due to a missing rosdep key for `mongdb` but this is listed in the rosdep: [rosdistro/rosdep/base.yaml at master · ros/rosdistro · GitHub](https://github.com/ros/rosdistro/blob/master/rosdep/base.yaml#L3406)

We have this building successfully on 14.04 ([http://build.ros.org/view/Ibin\_uT64/job/Ibin\_uT64\_\_mongodb\_store\_\_ubuntu\_trusty\_amd64\_\_binary/](http://build.ros.org/view/Ibin_uT64/job/Ibin_uT64 __mongodb_store__ ubuntu_trusty_amd64__binary/)) and 16.04 ([http://build.ros.org/view/Kbin\_uX64/job/Kbin\_uX64\_\_mongodb\_store\_\_ubuntu\_xenial\_amd64\_\_binary/](http://build.ros.org/view/Kbin_uX64/job/Kbin_uX64__mongodb_store __ubuntu_xenial_amd64__ binary/)), so I’m not sure what the issue us with 15.04. Anyone got any ideas?

thanks,

Nick

The key error is in the debian pipeline after rosdep has already been resolved by bloom.

Your problem is that mongodb does not have a armv8 version for Jessie. It has i386, amd64, and armhf: [Debian -- Error](https://packages.debian.org/jessie/mongodb)

 ![image](https://us1.discourse-cdn.com/flex022/uploads/ros/original/2X/6/680080d50976913d2d68a870d1ab652d47f65644.png)

So you’ll want to add this package to the jessie armv8 blacklist: [ros\_buildfarm\_config/kinetic/release-jessie-arm64-build.yaml at production · ros-infrastructure/ros\_buildfarm\_config · GitHub](https://github.com/ros-infrastructure/ros_buildfarm_config/blob/production/kinetic/release-jessie-arm64-build.yaml#L14) And then the buildfarm will stop trying to build the package.
