Bug report as per Reporting Guidelines required to be able to proceed here.
I found out that apparmor was blocking it despite valid configuration to allow onion-grater read /proc/cmdline. After reboot of Whonix-Gateway the issue is gone.
Recently I updated Whonix from bullseye to bookworm in the way described here:
Now I’m struggling with Whonix-Workstation because after upgrading from bullseye to bookworm Redis is not starting anymore. Again, it’s apparmor blocking Redis to load a shared library. This might not be Whonix specific issue or at some sort.
