And thanks for your solution to the dpkg-scanpackages issue. I ran it from the core as you suggested.
I also had success with the apt-key add, and dpkg-scanpackages command is not found on the MD.
But I had a problem with /usr/pluto/deb-cache reporting as read only (though mount shows it as rw) and it's not an issue since we can run it from core.
On the MD, apt-gt update did run without error with the apt-key add and the Packages.gz created on the core
But apt-get dist-upgrade had the same error as earlier with the twofish conflict.
Authentication warning overridden.

Anyone have any thoughts as to why twofish is conflicted?
