I have an rclone special remote that I can get my Windows computer to see, but it seems to be messing up actually getting the file:

By the looks of it, either the temp file that GPG uses doesn't get made, or it gets made but with incorrect contents:

$ git annex get --debug 'Samples/Recorded/1-Audio 0001 [2021-12-08 093649].aif'

I don't know how to proceed. As I understand it, shared encryption shares a key between the git repos. What file stores the shared encryption key so I could see if it's the same in both places?

Is there anything else obviously dumb I'm doing?
