Rootless docker: i/o timeout with docker pull

Docker Engine General
7

Dear all,

the wireshark-cli package does exist but I did a zypper in wireshark. The command provided gave :

someuser@somehost:~> nsenter --all -t $(pidof rootlesskit | awk '{print $1}') sh
nsenter: reassociate to namespace 'ns/cgroup' failed: Operation not permitted

Hence, I did a sudo on that, did docker pull hello-world in the rootless docker in another terminal which gave:

root:/ # nsenter -n -t $(pidof rootlesskit | awk '{print $1}') tshark -i tap0
Running as user "root" and group "root". This could be dangerous.
Capturing on 'tap0'
