PowerShell by Default. Kind of.

A while ago, we put PowerShell into Kali Linux’s network repository. This means if you wanted powershell, you had to install the package as a one off by doing:

kali@kali:~$ sudo apt install -y powershell

Kali on ARM Improvements

Not all of us are installing any location, so we highly recommend that you set your location. This can be done by running the following command, sudo dpkg-reconfigure locations, then log out and go back in.

Download Kali Linux 2020.2

Existing Upgrades If you already have an existing Kali installation, remember you can always do a quick update:

kali@kali:~$ echo “deb kali-rolling main non-free contrib” | sudo tee /etc/apt/sources.list
kali@kali:~$ sudo apt update && sudo apt -y full-upgrade
kali@kali:~$ [ -f /var/run/reboot-required ] && sudo reboot -f


You should now be on Kali Linux 2020.2. We can do a quick check by doing:

kali@kali:~$ uname -v

Switching Desktop Environments

kali@kali:~$ sudo apt update


kali@kali:~$ sudo apt install -y kali-desktop-kde


kali@kali:~$ sudo update-alternatives –config x-session-manager


If we choose to install KDE, we have to remember a few conflicts that might come up. We can have KDE installed alongside other DEs, however the way that the packages are currently configured there will be a few configuration conflicts. For example, when both KDE and Xfce are installed Xfce will not be able to have its cursor selected.

To work around this we will remove Xfce and only have KDE installed, and we do not advise having other DEs alongside it. Keep in mind that this only applies for KDE; you may have both Xfce and GNOME installed at the same time with no conflicts.

kali@kali:~$ sudo apt purge –autoremove kali-desktop-xfce
