I've posted a patch series to remove references to CENGN, and the cengn mirror from the master branch. The reviews are here ... https://review.opendev.org/q/topic:remove-cengn-refs When the tools update ... https://review.opendev.org/c/starlingx/tools/+/894826 .... merges, folk who update a pre-existing build environment via 'repo sync'  will need to run a few extra commands to fix your environment. # exit your debian build containers stx config --upgrade stx-init-env --rebuild # re-enter you build container No special commands are required when creating a new build environment. Any concerns?  I'll hold the tools update at WF-1 until after the next community call to give time for feedback. Scott
