Qubes-Whonix 16 has been Released! (Debian 11 bullseye based) - Major Release

Whonix : A High Security Method of Surfing the Internet

Whonix is a desktop operating system designed for advanced security and privacy. Whonix mitigates the threat of common attack vectors while maintaining usability. Online anonymity is realized via fail-safe, automatic, and desktop-wide use of the Tor network. A heavily reconfigured Debian base is run inside multiple virtual machines, providing a substantial layer of protection from malware and IP address leaks. Commonly used applications are pre-installed and safely pre-configured for immediate use. The user is not jeopardized by installing additional applications or personalizing the desktop. Whonix is under active development and is the only operating system designed to be run inside a VM and paired with Tor.

Significantly, Whonix ™ 16 is based on the Debian bullseye (Debian 11) distribution which was officially released on August 14, 2021 instead of Debian buster (Debian 10). The bullseye release has nearly 60,000 packages and around 72 per cent of them were updated.

This means users have access to many new software packages in concert with existing packages. In addition, this release will serve as a development foundation for many exciting upcoming security enhancements such as Hardened Malloc Kicksecure ™ (HMK), Linux Kernel Runtime Guard (LKRG) and other items on the Whonix ™ Security Roadmap.

Alternatively, in-place release upgrade is possible upgrade using Release Upgrade Whonix 15 to Whonix 16 instructions.

This release would not have been possible without the numerous supporters of Whonix!

Users report this problem just after installing whonix-gw-16 in Qubes (see the end of that forum post).

Therefore it should be either reported in the Qubes issues area, or added as a comment to an existing issue there (if appropriate).
