Do you get the same error if you try to decrypt it before moving the file? I 
tried with the exact same arguments with gpg 2.3.1, libgcrypt 1.9.4 and 
everything worked well (though I didn't try moving the files to another medium).

I also wonder if you're waiting until the file has been fully written (you can 
ensure this by running `sync` and waiting until it has returned) before trying 
to decrypt?
