Updating Your System

Before installing any new packages, it’s always a good idea to update your system’s package list. This ensures that you’re installing the latest version of the package and that all dependencies are met.

sudo apt update

The sudo command allows you to run commands with administrative privileges, while apt update updates the list of available packages and their versions.

Installing python3-docutils

Next, we will attempt to install python3-docutils. This package provides utilities for the Python Documentation Utilities project, which includes rst2man.

sudo apt install python3-docutils

The apt install command installs new packages. In this case, it’s installing the python3-docutils package.

Installing python3-docutils from Source

If the above command fails, you can try installing python3-docutils from the source. Here’s how:

  1. Download the source code for python3-docutils:
wget https://files.pythonhosted.org/packages/9d/1a/8a9e7d8a4e1a1e7a6e9c3b2d3a6b2f5b5a2e7a9e5f6e6e9e7e6e9e7a6e9e/docutils-0.18.tar.gz

The wget command is used to download files from the internet.

  1. Extract the downloaded archive:
tar -xf docutils-0.18.tar.gz

The tar command is used to manipulate tar archives. The -x flag tells tar to extract, and the -f specifies the file to extract.

  1. Change to the extracted directory:
cd docutils-0.18

The cd command is used to change the current working directory.

  1. Install python3-docutils using pip:
sudo pip3 install .

The pip3 install . command installs a Python package from the current directory.

Running the Configure Command

After installing python3-docutils, try running the configure command again for BlueZ:

./configure --disable-dependency-tracking

The ./configure command checks your system to ensure all dependencies for the installation are met. The --disable-dependency-tracking option speeds up the one-time build.

Installing rst2man

If the configure process still fails with the same error, you can try installing rst2man separately.

sudo apt install python3-docutils-common

This command installs the python3-docutils-common package, which includes rst2man.

Once installed, retry the configure command for BlueZ:

./configure --disable-dependency-tracking

Conclusion

By following the steps outlined in this guide, you should have successfully installed python-docutils and resolved the “rst2man is required” error in Ubuntu. If you still encounter issues, it’s possible that the required package is not available in the default repositories for your Ubuntu version. In that case, you may need to search for alternative sources or contact the software project for further assistance.

Remember, it’s always a good idea to keep your system updated and to install packages from trusted sources to maintain the security and stability of your system.
