I've recently extended the expiration date of my public key for a year, but=
=20
just noticed I forgot to extend the subkey as well. For no particular reaso=
n=20
I wanted to extend the expiry date of the subkey instead of creating a new=
=20
one, so I tried gpg --edit-keys <subkeyid>, 'expire' and set it to one year=
=20
from now - but the expiration date stays the same and now nobody can encryp=
t=20
with my key...

Am I doing something wrong, isn't this supposed to work, or is it a bug?
