I am trying to extend the expiration date of an expired GPG/PGP key, mainly using the results from this post. My steps look like this :
$ gpg --list-keys
pub rsa4096 2021-01-01 [C] [expired: 2023-01-01]
<KEY>
uid [ expired] myname myemail
$ gpg --edit-key <KEY>
gpg> expire
... (steping through)
gpg: signing failed: No secret key
gpg: make_keysig_packet: No secret key
I think the issue comes from the fact that I am trying to change the public key's expiration date by using that same (expired) key. It seems to me that I have no way to actually change the expiration date of my key.
Do you know how I can actually unexpire my key?
