Error while deploying the core network

[m-wojnar]

Dear 5G-Spector developers,

I have a problem while deploying the core network. I followed the installation instructions on the "5G‐Spector Artifact in a Simulated LTE Network" wiki page and was able to successfully download the VM, install the dependencies, and import and run the VM. However, when I run the make omen command, I get an error:

error: timed out waiting for the condition on pods/upf-0
mk/epc.mk:11: recipe for target '/home/vagrant/sdran-in-a-box//workspace/milestones/omec' failed
make: *** [/home/vagrant/sdran-in-a-box//workspace/milestones/omec] Error 1

Running the command kubectl get pods -n riab gives the result:

NAME          READY   STATUS             RESTARTS       AGE
cassandra-0   1/1     Running            0              7m37s

upf-0         2/4     CrashLoopBackOff   11 (34s ago)   6m21s

I tried following the troubleshooting section and restarting all services, but failed to resolve the problem with commands:

cd ~/sdran-in-a-box
make reset-test && make omec && make OPT=ric

I am using a fresh installation of Ubuntu 24.04 on an x86-64 machine.

Could you provide the log of the upf-0 container that has crashed?

For example: kubectl logs upf-0 -n riab --previous

[m-wojnar]

Of course, the command kubectl logs upf-0 -n riab --previous gives me an output:

error: a container name must be specified for pod upf-0, choose one of: [bessd routectl web cpiface] or one of the init containers: [bess-init]

Below are the outputs for the following containers:

• bessd

+ bessd -m 0 -f -grpc-url=0.0.0.0:10514

• routectl

Thanks for sharing the logs. It looks like the connection to the BESS daemon has failed. So far we haven't run into this issue and we could not offer a solution for this. We notice you have been running with ubuntu 24.04 as the host, which might be the problem. The SD-RAN RiAB environment has been tested on ubuntu 18.04 (https://docs.sd-ran.org/master/sdran-in-a-box/docs/HW_Installation_intro.html) so it might be better to use the same version.

[m-wojnar]

Thank you for your feedback. I'll consider downgrading to Ubuntu 18.04 as suggested and retesting the environment.

I'm also trying to simulate a 5G-Spector artifact in an LTE network, but I can't get the VM image, it shows that the link is expired, how do I get the image?
