Comment 1 for bug 1929899

I am unable to reprodce the problem on 21.04.
The command "ip address" does not give me any error.
Can you please confirm the version of "iproute2" you have..
In my system:
$ dpkg -l libbpf0 iproute2
ii iproute2 5.10.0-4ubuntu1
ii libbpf0:amd64 1:0.3-2ubuntu1

And, also what is the output from:
"nm -gDC /usr/lib/x86_64-linux-gnu/libbpf.so.0 | grep bpf_object__open_file" ?
