UE failed to setup/configure GW interface

[pchat-imm]

I follow this tutorial: O-RAN NearRT-RIC and xApp https://docs.srsran.com/projects/project/en/latest/tutorials/source/flexric/source/index.html

I used to successfully running it (open5gs -> nearRT-RIC -> gnb -> ue -> ping), until my ubuntu encountered problem and need to reset and installed everything again.

I finish installed and running

• 5gc (open5gs docker from srsRAN_Project)
• near-RT RIC
• gNB (from srsRAN_Project)

But I encounter problem when running srsRAN_4G, the PDU session cannot be established

My srsRAN_4G during cmake show zeromq disable by default

-- Checking for module 'ZeroMQ'
--   No package 'ZeroMQ' found

I try delete czmq and install again, and delete srsRAN_4G and install again but still encounter problem. Please help me. I attach log here.

you need to run:

sudo ip netns add ue1

Thank you, I forgot to add it before run the UE, I try to add it after and maybe that's why I could not successfully set PDU session. Thank you.
