Pip changes in Python

Python pip command is undergoing a change in Debian 12 Bookworm release (upcoming). The pip command is used to install Python modules. Since the modules are installed externally using pip, it might break the existing Debian installation.

Hence, from Debian 12 onwards, if you try to install any module using pip – you should get an “externally-managed-environment” error. See below.

The Kali Linux team is providing a patch from this release onwards to enable you to install any module using pip. But it is temporary until the Debian 12 stable release.

So, if you are a developer using a Python environment in Kali Linux (or in Debian), you should definitely plan to deploy the modules using the apt command as below.

apt install python3-numpy

Desktop environment and other updates

The default desktop Xfce now features Xfce 4.18 version, which brings massive features, including split view, image preview and others in Thunar file managers. Also, the KDE Plasma edition now arrives with version 5.27 in Kali Linux 2023.1.

The default theme in the Xfce edition is improved with stunning looks; many new wallpapers are also included in this version.

Finally, the mainline Kernel 6.1 is now available in this release, providing the latest hardware, CPU, GPU and other supports.
