Apt update : failed to fetch expkeysig abf5bd827bd9bf62 nginx signing key signing-key@nginx.com

apt update ，更新 nginx 时报错。 提示 Nginx 签名无效, 无法获取.

failed to fetch https://nginx.org/packages/mainline/debian/dists/bookworm/inrelease the following signatures were invalid: expkeysig abf5bd827bd9bf62 nginx signing key <signing-key@nginx.com>
解决处理：
  1. 导入 Nginx.org GPG 密钥：
curl -fSsL https://nginx.org/keys/nginx_signing.key | sudo gpg --dearmor | sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg > /dev/null

2. 验证密钥是否成功导入：

gpg --dry-run --quiet --import --import-options import-show /usr/share/keyrings/nginx-archive-keyring.gpg

3. 导入 Nginx.org APT 存储库

bash 下执行以下 echo 命令 :

（Mainline 存储库 、稳定存储库 二选一！）

要导入 Nginx Mainline 存储库，请使用：

echo "deb [arch=amd64,arm64 signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] http://nginx.org/packages/mainline/debian `lsb_release -cs` nginx" | sudo tee /etc/apt/sources.list.d/nginx.list

或者，对于 Nginx 稳定存储库：

echo "deb [arch=amd64,arm64 signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] http://nginx.org/packages/debian `lsb_release -cs` nginx" | sudo tee /etc/apt/sources.list.d/nginx.list

Debian 12 apt update GPG error: NO_PUBKEY

debian 11 版本更新 到 12，update出现两个错误。

①，Hit:5 https://packages.microsoft.com/debian/12/prod bookworm InRelease

Err:5 https://packages.microsoft.com/debian/12/prod bookworm InRelease
The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY EB3E94ADBE1229CF

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://packages.microsoft.com/debian/12/prod bookworm InRelease: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY EB3E94ADBE1229CF

解决办法：

1 下载 https://packages.microsoft.com/config/debian/12/prod.list 替换 /etc/apt/sources.list.d/microsoft-prod.list

2 直接修改 /etc/apt/sources.list.d/microsoft-prod.list 为以下内容：

deb [arch=amd64,arm64,armhf signed-by=/usr/share/keyrings/microsoft-prod.gpg] https://packages.microsoft.com/debian/12/prod bookworm main

② Hit:6 https://packages.sury.org/php bookworm InRelease

W: https://packages.sury.org/php/dists/bookworm/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.
W: Failed to fetch https://packages.microsoft.com/debian/12/prod/dists/bookworm/InRelease The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY EB3E94ADBE1229CF
W: Some index files failed to download. They have been ignored, or old ones used instead.
