Hitting <Ctrl-C> to quit did the trick. Now I could copy the key – a new
one – to two cards. Thanks for the suggestion!

Before that I tried re-importing the private key from the `.asc` file,
but it still was not possible to write it to another card. The error
message was the same as before. I don’t understand this: The key is
around, but somehow I cannot use it.
