Koneksi TLS ke marmalade-repo.org:443 tidak aman setelah memperbarui ke Emacs 25

Ketika saya menjalankan, M-x list-packagessaya mendapatkan kesalahan berikut dengan Marmalade setelah memperbarui ke Emacs 25.

Certificate information
Issued by:          COMODO RSA Domain Validation Secure Server CA
Issued to:          Domain Control Validated
Hostname:           marmalade-repo.org
Public key:         RSA, signature: RSA-SHA256
Protocol:           TLS1.2, key: ECDHE-RSA, cipher: AES-256-GCM, mac: AEAD
Security level:     Medium
Valid:              From 2015-07-12 to 2018-07-11


The TLS connection to marmalade-repo.org:443 is insecure for the
following reasons:

the certificate was signed by an unknown and therefore untrusted authority
certificate could not be verified

Saya juga sudah mencoba menyelesaikannya dengan saran gnutils-cli : $ gnutls-cli --tofu marmalade-repo.orgtetapi belum berhasil. Ada ide?

Masalah yang belum terpecahkan terkait : Konfigurasi server TLS rusak dan rentan # 144

Konfigurasi server pada marmalade.org rusak: Tidak melayani sertifikat perantara yang digunakannya. Ini telah ditunjukkan dalam setengah lusin masalah sekarang di https://github.com/nicferrier/elmarmalade - Saya tidak bisa melihat tindakan apa pun.

Jadi dapat dikatakan bahwa selai sudah mati.

Sayangnya, saya juga belum tahu bagaimana cara membuat manajer paket Emacs bekerja lagi di hadapan kesalahan ini.

Saya mendapatkan ini berfungsi dengan mengunduh file PEM untuk [Intermediate CA # 2] COMODO RSA Organization Validation Secure Server CA (SHA-2) ke dalam ~/etc/tls/certificates/comodo.rsa.ca.intermediate.crtdan menambahkan yang berikut ke .emacs:

  (require 'gnutls)
  (add-to-list 'gnutls-trustfiles
               (expand-file-name
                "~/etc/tls/certificates/comodo.rsa.ca.intermediate.crt"))
