Python Updates & Changes

Debian is getting ready to release its next stable version, which means packages are being updated. Python is one such package, with Python 3.11 now available in Debian. This new version brings more informative error tracebacks and a significant speed increase. However, some older packages may not be supported with the upgrade.

One change that may catch people off guard is Python’s PIP behavior. Using PIP to install Python modules can clash with the operating system’s package management system, apt. To avoid this issue, users have three options:

  • Use apt install python3-<package> (easy, simple & recommended)
  • Use venv (slightly more complicated but still recommended)
  • Use -break-system-packages (warning warning warning!)

Kali Linux has applied a temporary patch to give users more time to adjust their procedures. However, this patch will be dropped with the release of Kali 2023.4 in the fourth quarter of this year. After that, PIP will refuse to install packages system-wide, and users will need to use one of the recommended options mentioned earlier. Kali Linux will remind users of this change with each version building up to the release. It is important to update scripts, pipelines, and documentation to the recommended ways to avoid issues with the new Python update.

Theme Refresh

Kali Linux 2023.1 has a brand new theme with updated wallpapers for the desktop, login, and boot displays.

It would not be a Kali release if there were not any new tools added! A quick run down of what has been added (to the network repositories):

There have also been numerous packages updates and new libraries as well. We also bump the Kali kernel to 6.1!
