Thanks Yong!
13:37:39 ERROR: Could not find useradd in chroot, maybe the install failed?
It looked the local repo failed to be created. please check and assure "~/cgcs- root/cgcs-centos-repo/Binary/comps.xml" is there, and the sub-dirs in ""~/cgcs-root/cgcs-centos-repo/Binary/" do exist with correct symbol links to the mirror.
I have checked comps.xml and it is there, the symbolic links were also updated using our script update_links_from_mirror.sh. Team here in Mexico have started the building only from external sources yesterday. 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. 2 changes for stx-tools not yet merged to integrate to complete a full external build: - cgcs-centos-repo: https://review.openstack.org/#/c/579709/ - cgcs-dl: https://review.openstack.org/#/c/577953/ Do not hesitate to provide any feedback or modify our wiki as required.
