trying to get the gpg keys from my #deltachat and I think I got them from the deltachat export sqlite, but copying them into a file doesn't seem to be working. I can't get around

gpg: no valid OpenPGP data found.

the url https://linuxier.com/fixes-for-gpg-no-valid-openpgp-data-found/

tells me I've hit a rabbit hole.
