<p>Hello all,<br>
<br>
I'm trying to import a key generated from GPG 2.4.4 to 2.2.27 but
unsuccessful.<br>
<br>
Upon importing, it returns `gpg: no valid OpenPGP data found.`<br>
<br>
I tried with compliance options but it does nothing.<br>
<br>
Command I used:<br>
<br>
- export: `gpg -a --export-secret-subkey <key_id> | gpg -a
-c --cipher-algo AES --force-mdc -o <file>`<br>
- import: `gpg --decrypt -o - keys.sec.asc | gpg --import -`<br>
<br>
What else I can do? I can't update the GPG version because one of
my<br>
import device is an Android phone which stuck at 2.2.27 for quite
a long<br>
time.<br>
</p>
<p>Regards,<br>
Hartman<br>
