The developers of Kali Linux, a forensics and security distribution based on Debian, have released Kali Linux 2.0. One of the big changes in the latest version of Kali is that the distribution has shifted to a rolling release model. “One of the biggest moves we’ve taken to keep Kali 2.0 up-to-date in a global, continuous manner, is transforming Kali into a rolling distribution. What this means is that we are pulling our packages continuously from Debian Testing (after making sure that all packages are installable) — essentially upgrading the Kali core system, while allowing us to take advantage of newer Debian packages as they roll out. This move is where our choice in Debian as a base system really pays off — we get to enjoy the stability of Debian, while still remaining on the cutting edge.” The new release of Kali Linux is available in 32-bit and 64-bit x86 builds as well ARM builds.
How Do I Upgrade to Kali 2.0?
Yes, you can upgrade Kali 1.x to Kali 2.0! To do this, you will need to edit your source.list entries, and run a dist-upgrade as shown below. If you have been using incorrect or extraneous Kali repositories or otherwise manually installed or overwritten Kali packages outside of apt, your upgrade to Kali 2.0 may fail. This includes scripts like lazykali.sh, PTF, manual git clones in incorrect directories, etc. – All of these will clobber existing files on the filesystem and result in a failed upgrade. If this is the case for you, you’re better off reinstalling your OS from scratch.
Otherwise, feel free to:
cat << EOF > /etc/apt/sources.list deb http://http.kali.org/kali sana main non-free contrib deb http://security.kali.org/kali-security/ sana/updates main contrib non-free EOF apt-get update apt-get dist-upgrade # get a coffee, or 10. reboot
