I did not ask because I wanted to blame anyone, but asked so I can solve a problem
The above instructions are what they SHOULD be and this is HOW THEY WERE.
Since the keyring was not updated prior to the shift to amprolla3 all the merged repositories were invalid, and this is where the new keyring was.
Only by switching the merged into devuan was I able to update the key, I just didn't realize I had to rechange back to merged. But merged were inaccessible without the key.

Why not go and delete your /etc/apt/trusted.gpg.d and see if you can install the keyring from /merged
I couldn't! I could from /devuan!
If that is true then the instructions to switch from Debian/jessie to Devuan/jessie with onion addresses are invalid. So try not to shove this under the carpet, yet.
In any case my question was about -ascii and -ceres not about -jessie but I will have to make the deduction, which has proven many times in the past to be false.
