@hubitor That’s because the package that’s in Arch Linux explicitly disables the security sandbox when it detects that user namespaces are disabled.

To fix this, follow the instructions on the stable package page:

sudo sysctl kernel.unprivileged_userns_clone=1
echo kernel.unprivileged_userns_clone = 1 | sudo tee /etc/sysctl.d/00-local-userns.conf
