After debugging this, I found a spurious port, which was renamed, and it all started working. Thanks From: James Tervit Date: Thursday, 18 January 2024 at 13:22 To: dev@dpdk.org Subject: Ubuntu Upgrade 20.04.6 to 22.04 Jammy 23.06 HomeGateway example Dear DPDK Folks, I am following the latest build of home gateway https://s3-docs.fd.io/vpp/23.06/usecases/home_gateway.html for testing and development. Running Linux PXC-SM-002 5.15.0-91-generic #101-Ubuntu vpp/jammy,now 23.10-release amd64 [installed] PRETTY_NAME="Ubuntu 22.04.3 LTS" NAME="Ubuntu" VERSION_ID="22.04" VERSION="22.04.3 LTS (Jammy Jellyfish)" In my vpp startup.conf, which is calling setup.gate and, in turn, runs setup.tmpl I get an error on systemd in bold below.

I can bind ports and unbind back to kernel with no problem, and I can see the interfaces inside vpp and bvi look ok. sudo vppctl show interface, ip addresses not assigned as I think that’s because the script doesn’t process the lstack and dhcp portion due to crashing.
