How To Fix umoci: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu umoci is provided by umoci package.

umoci is:

umoci creates and modifies Open Container images. See the official website (https://umo.ci/) for more accessible documentation about how to use umoci.

umoci intends to be a complete manipulation tool for OCI images (https://github.com/opencontainers/image-spec). In particular, it should be seen as a more end-user-focused version of the oci-image-tools provided by the OCI (https://github.com/opencontainers/image-tools). The hope is that all of this tooling will eventually be merged with the upstream repository, so that it is always kept up-to-date by the Open Container Initiative community.

umoci provides tooling that can abstract all of the internals of the OCI specification into a single CLI interface.

To fix this problem, we can install more using the command below.

sudo apt-get -y install umoci

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install umoci.

sudo apt -y install umoci

sudo aptitude install umoci
