'sctp::SctpError' SCTP socket could not be created

[kiki639]

Hi, I'm using Open5GS and UERANSIM to study 5G.

I installed Open5GS on server, and UERANSIM on Raspberry Pi. Both used Ubuntu server 22.04 as operating system.
And when I run the gNB of UERANSIM in raspberry pi, the following error occurs.

~/UERANSIM/build$ ./nr-gnb -c ../config/open5gs-gnb.yaml
UERANSIM v3.2.6
[2024-09-05 14:36:55.710] [sctp] [info] Trying to establish SCTP connection... (192.168.1.153:38412)
terminate called after throwing an instance of 'sctp::SctpError'
  what():  SCTP socket could not be created
Aborted (core dumped)

It's called the SCRP socket problem, but I don't know how to solve it.
Does anyone know the answer?

I've solved this problem.
I leave it for people who will have the same problem.

It appears that there is a problem between the kernel and the module when using the operating system Ubuntu 22.04.
I solved the problem by performing the following command.

sudo apt-get install linux-modules-extra-$(uname -r)
sudo modprobe sctp

good luck!
