# Installing NDCTL and DAXCTL Packages on Linux

The `ndctl` and `daxctl` utilities are available in many Linux distribution package repositories.  This approach is the easiest to use and maintain, compared with [installing ndctl from source code](https://docs.pmem.io/ndctl-user-guide/v70/installing-ndctl/installing-ndctl-from-source-on-linux). The daxctl utility is bundled with the ndctl packages.

{% tabs %}

{% tab title="Ubuntu" %}
The ndctl package is available on Ubuntu 18.10 (Cosmic Cuttlefish) or later.

1\) Query the repository to identify if the ndctl package is available using either the aptitude, apt-cache, or apt utilities
