How To Fix dials.data: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu dials.data is provided by python3-dials-data package.

python3-dials-data is:

Lightweight, simple Python(-only) package. It is used to provide access to data files used in regression tests, but does not contain any of those data files itself.

Although it is envisaged as mostly being used in a cctbx/DIALS environment for tests in DIALS, dxtbx, xia2 and related packages, it has no dependencies on either cctbx or DIALS, in fact all dependencies are explicitly declared in the setup.py file and are installable via standard setuptools/pip methods. This means dials_data can easily be used in other projects accessing the same data, and can be used in temporary environments such as Travis containers.

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

sudo apt-get -y install python3-dials-data

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

You can also use apt command to install python3-dials-data.

sudo apt -y install python3-dials-data

Or if you have aptitude installed you can use the following command.

sudo aptitude install python3-dials-data
