When I run podman I get,

$ podman info
cannot clone: Operation not permitted
user namespaces are not enabled in /proc/sys/kernel/unprivileged_userns_clone
Error: cannot re-exec process

How can I enable user namespaces and have them persist after reboot? I am using Debian.

You can enable user namespaces like this,

sysctl -w kernel.unprivileged_userns_clone=1

And you can have it persist after reboot in Debian by running this,

echo "kernel.unprivileged_userns_clone=1" >> /etc/sysctl.conf
