Hi Abraham, Did you run "build-pkgs" or "build-pkgs --serial"? If I run "run-pkgs" (parallel mode) I saw the similar errors as you did, but if using "-- serial" the build went smoothly and further, except for failures on following 3 packages, which is known issue. 13:42:03 Failed to build packages: memcached-1.4.39-1.el7.tis.1.src.rpm kubernetes-1.10.0-1.tis.1.src.rpm python-2.7.5-58.el7.tis.3.src.rpm In the meantime, @Zhipeng is following steps in https://wiki.openstack.org/wiki/StarlingX/Developer_Guide On 04/07/2018, 7:02 AM, "Arce Moreno, Abraham" <abraham.arce.moreno@intel.com> wrote: > > > > It will be great if someone else could take our Developer Guide > > > > https://wiki.openstack.org/wiki/StarlingX/Developer_Guide > > > > and build the ISO from scratch. > > Yeah, we will have someone to do the exercise based on this guide.
