최근에 emacs 패키지를 업데이트하려고했는데 이것을 얻었습니다.
Failed to verify signature archive-contents.sig:
No public key for 066DAFCB81E42C40 created at 2019-10-02T10:10:02+0100 using RSA
Command output:
gpg: Signature made Wed 02 Oct 2019 10:10:02 AM BST
gpg: using RSA key C433554766D3DDC64221BFAA066DAFCB81E42C40
gpg: Can't check signature: No public key
어떤 아이디어가 있습니까?
