Hi Konstantin,

Most subkey changes that I am aware of are not due to people's old subkeys expiring, but because they add new ones for reasons like migrating between smartcard solutions or just being nerdy and picking a new ECC-based subkey.

When this happens, a maintainer who tries to verify a signed pull request will have the operation fail, so they need to have a way to force-refresh the developer's key.

Do you mean something simpler than [0]:

gpg --auto-key-locate clear,wkd,nodefault --locate-key torva...@kernel.org

?

Trying key lookup over WKD if the subkey is missing locally (but primary key is present) would be a good idea. I've seen some really weird errors in that case [1].

If the primary key used short expiration [2] the refresh would be automatic but not many people like to prolong expirations every couple of months.

Kind regards,
Wiktor
