Hi,

I'm trying to install 5gs on k8s cluster which is on ubuntu 20.04. building gtp5g was successful with kernal "5.4.0-159-generic"

In values.yaml, I've modified eth0/eth1 with ens33/ens34 interface name. Attaching, ip-info, upf-logs, smf-logs, all k8s pod in all namespaces. Appreciate if someone can point me in right direction and help sort this out.

upf-logs.txt ip-info.txt k8s-pod-details.txt smf-logs.txt

After couple of tries of install helm chats, primarily issue is with UPF. Seeing below error. 2023-09-01T07:27:12.748483949Z [INFO][UPF][CFG] ================================================== 2023-09-01T07:27:12.748493158Z [INFO][UPF][Main] Log level is set to [info] 2023-09-01T07:27:12.748501178Z [INFO][UPF][Main] Report Caller is set to [false] 2023-09-01T07:27:12.748580507Z [INFO][UPF][Main] starting Gtpu Forwarder [gtp5g] 2023-09-01T07:27:12.748596109Z [INFO][UPF][Main] GTP Address: "172.17.192.233:2152" 2023-09-01T07:27:12.819948480Z [ERRO][UPF][Main] UPF Cli Run Error: open Gtp5g: version mismatch: operation not supported

It was related to some k8s networking issue coupled with cni plugins. It's all sorted and able to install successfully.
