Tidak dapat menyelesaikan kesalahan GPG

Saya berlari sudo apt-get updatedan pada akhirnya saya memiliki kesalahan ini:

Sepertinya kunci saya yang hilang adalah:

• 40976EAF437D05B5
• 3B4FE6ACC0B21F32
• 16126D3A3E5C1192
• A040830F7FAC5991
• A8A515F046D7E7CF
• E131728675254D99

Saya melihat sebagian besar jawaban mengatakan untuk menjalankan:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys [MISSING KEY]

Saya berlari itu:

Aku bisa melihat unchanged: 1.
Saya juga mencoba menggunakan y-ppa-manageritu juga tidak menyelesaikan masalah.

Apa yang menyebabkan kesalahan ini dan bagaimana saya bisa menyelesaikannya?

Ini seperti bug berikut bagi saya.

Bagaimana cara memperbaiki

Dari pengguna yang memperbaikinya dalam laporan bug:

Solusi yang bekerja untuk saya adalah mengosongkan /etc/apt/trusted.gpg.d, menjalankan pembaruan apt-get, dan kemudian secara manual menambahkan setiap kunci yang diblokir ke /etc/apt/trusted.gpg keyring utama dengan apt-key adv seperti dijelaskan di atas.

Jadi, dalam kasus Anda, Anda harus melakukan hal berikut (penafian: tidak bisa mengujinya):

sudo mv /etc/apt/trusted.gpg.d/ /etc/apt/trusted.gpg.d.backup
sudo mkdir /etc/apt/trusted.gpg.d
sudo chmod 755 /etc/apt/trusted.gpg.d

Kemudian, untuk setiap tombol yang Anda butuhkan:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 40976EAF437D05B5

tempat Anda mengganti hash dengan hash kunci yang dibutuhkan. Seperti yang dicatat Ionică Bizău, beberapa kunci dapat ditambahkan, dipisahkan dengan spasi.

Kenapa itu muncul?

Rupanya, gpg hanya dapat menangani sejumlah kunci, dan instalasi Anda membutuhkan lebih banyak. Mungkin, ini disebabkan oleh memiliki banyak sumber paket alternatif.

Sekali lagi, dari laporan bug:

I asked about the "resource limit" message on the gnupg-users mailing list...
Based on Werner Koch's (the dev) answer...
...the secure apt related programs might be making gpg use more than the maximum number of keyrings that it can handle

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys [MISSING KEY] bekerja untukku.
