I’m using Qubes-Whonix, and I just received this message in both whonix-gw and whonix-ws. I didn’t manually uninstall any packages. All I did was allow my automatic background TemlpateVM update script to run, as it does every day. In whonix-* TemplateVMs, it just does the standard apt-get -y update && apt-get -y dist-upgrade.
