GPGエラーを解決できません

私は走っsudo apt-get updateたが、最後にこれらのエラーがあります：

私の不足しているキーは次のとおりです：

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

私は答えのほとんどが実行すると言うのを見ました：

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

私はそれを実行しました：

私もそれを使用しようとしましたがy-ppa-manager、問題も解決しませんでした。

これらのエラーの原因と解決方法を教えてください。

これは、次のバグのように見えます。

直し方

バグレポートで修正したユーザーから：

私のために働いた解決策は、/ etc / apt / trusted.gpg.dを空にし、apt-get updateを実行してから、それがブロックしたすべてのキーをapt-keyでメインの/etc/apt/trusted.gpgキーリングに手動で追加することでした上記のadv。

したがって、あなたの場合、次のことを行う必要があります（免責事項：テストできませんでした）。

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

次に、必要なキーごとに：

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

ハッシュを必要なキーのハッシュに置き換えます。IonicăBizăuが述べたように、スペースで区切って複数のキーを追加できます。

なぜ登場したのか

どうやら、gpgは限られた数のキーリングしか処理できず、インストールにはさらに多くのキーリングが必要です。おそらく、これは多くの代替パケットソースを持つことによって引き起こされます。

繰り返しますが、バグレポートから：

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] 私のために働いた。
