Whonix 15 has reached EOL
https://www.qubes-os.org/news/2021/11/14/whonix-15-eol/

Whonix 15 has reached EOL (end-of-life). If you have not already done
so, we strongly recommend upgrading your Whonix 15 templates and
standalones to Whonix 16 (https://www.qubes-os.org/news/2021/09/30/whonix-16-template-available/) immediately. The Whonix Project provides
fresh Whonix 16 template packages through the Qubes community template
repositories, which you can install in dom0 by following the standard
installation instructions (https://www.whonix.org/wiki/Qubes/Install). Alternatively, the Whonix Project also
provides step-by-step instructions for performing an in-place upgrade (https://www.whonix.org/wiki/Release_Upgrade_Whonix_15_to_Whonix_16)
of an existing Whonix 15 template. After upgrading your templates,
please remember to switch all qubes that were using the old template
to use the new one (https://www.qubes-os.org/doc/templates/#switching).

For a complete list of template releases supported for your specific
Qubes release, please see our supported template releases (https://www.qubes-os.org/doc/supported-releases/#templates).
