Note that this is a very outdated mirror of http://git.infradead.org/?p=users/hch/nvmetcli.git, but I'll leave a few remarks for search engine users.

The issue you ran into is probably that the /usr/bin/python referenced in the shebang of ./nvmetcli does not exist.

Then you most likely at least need to install https://github.com/open-iscsi/configshell-fb. The code can handle a lack of https://github.com/cnanakos/kmodpy but without it you will need to load the nvmet kernel module manually.

Do not trust me on this, but users of recent Debian-y distributions might be able to get away with sudo apt install python3-configshell-fb && sudo modprobe nvmet && sudo python3 ./nvmetcli.
